Turbocharged vehicle tuning involves systematically adjusting boost pressure settings (low boost around 12 PSI, high boost around 20 PSI) and RPM thresholds (low boost at 5,500 RPM, high boost at 7,800 RPM) to optimize power delivery while maintaining drivability and reliability, with the tuner monitoring parameters like lambda targets and wastegate behavior to achieve the desired performance characteristics.

Street Tuning Sheela with Hagen PerformanceHinzugefügt:
Same thing. Let's see what it makes.
Heading out to Alex's house right now.
He's got a little spot that we can do some tuning and then he has a garage that we can run back to if we need to.
And then hopefully we can get some work done on his YXZ so we can go rip some Z's together. Yeah, I'm super stoked.
Last night we did all of the sensor calibration and all that. Sick brakes, brother. We got the sensor calibration all done with Josh Hagen and then today at noon we tune. If you don't know who Alex is, he's the one that pilots this beast.
So, it looks like you got some stuff going on. Dude, I got a mess is what I got. That's why I haven't been doing anything. Nobody's seen it for a while is cuz you work so much and then you just do a project here, a project there, and now you can't even work on projects cuz you got so much junk everywhere. But here pretty soon, I'll get everything all cleaned up, and span. You know how it's supposed to be. And we'll start working on this thing again. I mean, I we got a diff that wouldn't fit, so we're going to make it fit. I mean, we got bunch of extra tubing. I started a little bit of it, so we cut out one of the engine mounts right up there. We're going to cut out the other one, make a custom mount for uh some other stuff later. And then we're going to fill all this back in. And right here, I've got the new new new diff. So, hopefully this one will hold up a little bit better than the other one. We'll see.
>> That'll be slick.
>> We got that custom drive line we got to build. You got to move the trans. Um, yeah, that's just to get it running again. Then then we're going to modify like we normally do. Like we don't for some reason I can't just leave anything alone. So, I'm sure there'll be a lot more coming once once we get it rolling again.
>> There's more to modify to this thing.
>> Oh, yeah. There's always there's always more. We can always find something.
>> I'm most excited for the stuff that's hiding up there.
>> Oh, yeah. The super secret stuff.
>> Oh, >> that's all the It's no secret.
>> Oh, okay. I was like, I'll cut that one out.
>> No, people know, but they they know, but they don't know. So, I mean, all that stuff is a complete setup from uh Pivotal Motorsports. It's been out a little bit, but not too many people have seen the whole the whole car yet. You know, Avid had one. Um, this one's a little bit different than Avid setup.
So, I think you guys will be pretty excited to see when it comes out, see what you think of it.
>> I'm super excited. And that's because I got I got a little bit of the details, but also anything that Alex builds is kind of like over and beyond. This is not a normal YXZ by any means.
>> I don't know if you can even call it a YX YXZ anymore. It's more of a like a wolf in sheep's clothing. Like there's a YXZ body on whatever you want to call this Frankenstein at this point. There's there's not a ton of YXZ left on it. I mean, it's YXE drivetrain. some YXZE uh fenders basically. You know, there's there's not much left. It's >> there's a little bit of the frame still back in here. Well, maybe not.
>> Yeah, you got the stock you got the stock fuel tank. That's about it, you know.
>> Yeah.
>> Kind of a stock YZ looking cockpit, but even that's going to change here pretty soon. She'll be out again.
>> Well, let me know. Come out and shoot some video you building all this cuz >> absolutely >> people need to see this thing.
>> Yeah. Yeah, I got to clean up my mess from all my half projects everywhere first.
>> Alex is a busy guy. My garage looks like this and I have time. So, >> yeah. 90 hours in 6 days since September every week. You don't have a lot of time for doing much else. That's what funds these things, you know.
>> Yeah.
>> Sometimes you got to work hard to play hard.
>> All right, we got the desk set up. See, what he ends up doing to the center. We got one open road right here. Make a couple passes on. Well, here we go.
Wow. This is crazy, dude.
>> Is it?
>> Yeah.
>> You can hear my wastegate really working now, though. Yeah.
>> Now you're like getting right just right into it. I'm sure it'll sound pretty nasty once you get to it.
>> I know. I think all these years of me tuning it, I've been just doing stuff wrong. Probably.
>> But I was learning something, you know.
>> Yeah. All right. So Josh is texting us what to do.
>> It's pretty cool how he could just do this remotely from wherever he is.
Or did he just say that? Okay, let's do 3/4 throttle to 8K. 3500 to 8K. Third gear.
How much throttle? Uh 3/4 throttle.
Started on 3500 in third gear.
I >> will say though when he tunes it's like super thorough.
>> That is nice.
>> Yeah.
>> I'd rather have it over.
>> Like that's how you know that you're going to get a quality tune cuz we're going to be here forever.
>> I just thought I should have asked more questions.
>> I'll be like, "Hey, do I need to like pack a lunch before I go tuning or what?"
>> Yeah.
>> Are snacks provided? They should have provided juice fast.
>> I know, right?
>> 3580%.
>> Yeah. 3500 AK third gear, 3/4 throttle.
We're out here racing cornrows like Connor.
All right, first full throttle pull.
Here we go.
First full throttle right in the books there.
>> Yeah. I I wonder how much loose that was. It felt pretty slow.
>> You should be able to see it right in there. Like he's looking at lambda target.
>> Whose target was 26 PSI about minus 13?
>> Yeah. Minus like 14. 14 lb. Yeah, >> I really wanted to set this up. So, low boost will be 12 lb, high boost will be 20.
>> There you go.
>> So, it'll go straight to violence.
>> Well, I'm sitting here like full throttle. I'm like, that's it.
>> Yeah, >> that's all I got.
>> That's how I felt though, too.
>> Yeah, >> it felt slow, but he's figured it out.
>> Mine's just so violent.
>> Oh, yeah.
>> That's the problem. When it comes on, it's like the front end comes off the ground. You're like hanging on for dear life. one like you being on big tires and everything.
>> Yeah.
>> Your third gear probably reels out pretty far, too. So, you get quiet.
>> Oh, the suspension. It's got so much travel that like the front end's in the air, but the tires are still on the ground.
>> Yeah.
>> So, it just feels like you're just like going to the moon every time the turbo hits.
>> What did What did your car originally make the first time you had it done?
>> It made 420 and 22 PSI. That's what it said. And that was before the new turbo, the all the other engine work and everything we did. Different tuning now.
>> Yeah.
>> So, I'm really I want to put it on the dyno and see what it makes now. I mean, now, you know, cap was 22 psi. We're now at like 36 >> with a better turbo.
>> Yeah.
>> Yeah.
>> So, you're you're up there in power.
>> Oh, yeah. Dude, it's it's nasty. It's going to be cuz I'm hoping we crest five. That's what I'm hoping for. We'll see. Five in that chassis feel awesome.
>> Yeah.
Little bit of tuning going on. I want to keep the car just a solid tuner.
>> As much as I want to like make big power.
The best part is is I get in this, I beat the piss out of it, then put on the trim.
>> Well, that's the thing, too. It's like yours drives back on the trailer every weekend.
>> Yeah. That's I want to find that good threshold. I don't know what it is. 300 sounds like you can have a reliable day.
>> Whatever it is, it's less than mine.
>> Yeah, >> mine's too much.
>> I think 300 in you might you might break 300 horsepower.
>> Pro probably.
>> You like the party.
>> That's a problem. I just drive it too hard. I just need to put it back to NA with all the suspension. Just like max effort everything all the time.
>> Yeah. Okay. Full throttle fourth.
>> Full throttle fourth. All right.
get all set up. It's going to get a little more rowdy now.
Yeah, that one's way better. We'll have another shot here in a minute. Looks like he's up in the boost, so we get to try it again.
It sounds too good. I drive it.
>> Yeah, the gauge said like 12. Not sure how accurate it is compared to what the MTOR's saying, but should be pretty damn accurate.
>> So, you're just over like 12, almost 13, 12.8.
>> Yeah. Dude, >> I know. You should have gone standalone so much sooner.
>> Oh my gosh. I should have >> that flutter. I've always heard that on your car.
>> Yeah, >> the wastegate flutter. And it sounds so sick.
>> Yeah. It's all the standalone stuff.
There's so much more you could do with it that you can't do with the, you know, the pod 360 or 300 or the the power vision.
>> Yeah.
>> Like you could do some, but it's just kind of you just kind of band-aid it.
Whereas this, you can do it, right?
>> Yeah.
>> Okay. So, sorry. I try to send a different text each time. Ready for another pull.
>> That was 15.
So I saw on the gauge probably 15 16.
What do you run now? You run back now.
Yeah. Oh, and I hope they're connected, right? I just followed what the internet said.
>> I mean, it it's working.
>> That's what that difference is. That little bit of flutter is cuz that Mac valve is just opening, you know, a couple hundred times a second. Just that little bit. Ready for another full throttle pull.
There we go.
Starting to get there.
>> Yeah, you're probably 18, 19 right there. See where you were at.
Oh, no. Right about 17.
All right. He says, "Ready. This is high boost level. Don't change the switch.
Full throttle to red line."
I better hold on. Hang on. Let me get the laptop so I don't lose it. All right, clear. Here we go.
So, it's 17. So, it was the same as last time.
Start right here.
>> We just jump over.
>> Did we?
>> Yeah. All the bugs were hold.
>> All right, never mind. Try it again. We forgot to turn it up.
Hang on. Not yet.
>> Oh, all right. Yeah, he's changing. I was just talking to the camera. Oh, I know.
Oh, yeah. That's one more rowdy. Let's see what she does now. All right, 2 PSI shorter target. Let's see if we can get there. One more pull.
All right, hang on. Let me down the hatches.
Dad 22. Let's see what it says.
Yeah, it's about 21. I'll be I'll be 100% honest with you though. I think having us together is a terrible idea.
>> Yeah, this isn't a good idea >> cuz you and I drive the same and I think if we continue to drive together like we're not going to have anything to drive.
>> I don't know. I think if you turn your boost down a little bit >> Yeah, maybe >> that might help.
>> What's the fun in that?
>> I know.
>> That's the thing though. It's like you just got to make sure you got enough buns to continue throwing it at the fire.
>> Yeah.
>> You know, it's like that freight train where you're just shoving coal in it.
You know, it's just >> chug in the >> Yeah, it's just lots of cash.
>> Yeah.
>> Just don't ever let that fire go out.
You can drive it however you want.
>> See, my limitation is the suspension.
>> Yeah.
>> That helps keep my engine alive, too.
>> Yep. That's my problem is like I got all the suspension in the world, so I could drive it like like a complete degenerate.
>> Yeah.
>> And it the chassis will just take it.
>> Okay. Good between shifts.
Was it good between the shifts?
>> I'm good.
>> Low boost could be as low as 6 psi, 8 psi, or altitude. Do you want it that low?
>> And right now, you are max boost for the spring you have for high boost.
>> So, how much boost do you want on on low?
>> 12.
>> 12.
>> Yeah.
>> Think if you're max effort at, you know, 24 25 or you're just you're wastegate limited, that's like the best thing.
>> Yeah. So that way you know it'll never over boost even if the wastegate's stuck shut. Like you're just you're good, you know.
>> So right now that's how it's set up though.
>> Yeah. So right now you're maxed out with your wastegate.
>> All right. Time to play a little bit launch control. Here we go.
>> Dude, I'm stoked for this.
>> Yeah. Let's see what he changes it to.
7,800 RPM.
>> That's going to be rowdy.
>> Yeah. All right. Go ahead and try the two-step.
Put it in gear. Hold the button and then floor it.
It's pretty rowdy, isn't it?
My throttle sticking.
>> Is that mine? Did too.
>> You got to lift it.
>> You still got the the original 16 cable or 18 cable.
>> Yeah.
>> Yeah. Supposedly there was a recall on it. Oh, can he set it up on the high low switch?
>> I'll ask him and see what he says.
>> I think he could. He could just reference that signal.
>> I would think so, >> dude. Let's go. Thank you for coming out and helping.
>> Yeah, man. You're welcome. Dude, that's going to be rowdy. It made 20 lb.
>> That's going to be >> on the twostep.
>> Oh, it did?
>> Yeah, that's what I was just seeing. It made 20 lb on the twostep.
That's going to be third gear launches.
>> He says yes. What do you want?
>> So, do you want lower on low boost?
>> Yeah. 55 on low.
55 on low.
And then what do you want on high?
>> 75 high or 78? Whatever that was.
I said let's do 5500 on low, 7,800 on high. Does that seem right? 5200 is probably good for low. Try it on low.
Do it one more time. See what it takes.
Yeah. So, you made like 9 lb. Your turbo comes on so quick, though.
>> Yeah.
>> That like 9 lb is it's going to be rounded. It's going to be way rounded cuz you're only going from 9 to 12.
>> Yeah.
>> So, it's like it's going to be instant right right off the get go. It's going to be like all it's gone.
>> Wow.
>> So, it's going to be like it's going to be like Ricky's car but actually cool.
>> Yeah.
>> Yeah.
>> Yeah.
>> You don't need >> all that instant that instant torque and boost.
>> Yeah. You don't need a supercharger if you got this button.
>> Yeah. I mean, that's all you need.
>> Yeah.
>> You even got the belt squeal like Ricky does.
>> Hey, we finally calmed down. Now it's warm.
>> Yeah, now that it's all warmed up, what we need in this thing is some air conditioning. It's freaking hot out here. High low again.
Oh yeah. Hold it out just a little bit longer.
That's 10 lb.
Dude, that is nasty. That rowdy.
Now we're going to switch to high.
We're going to flip on the high and then same thing. Let's see what it makes too.
Yeah. So, that was that was about 11 lbs on high.
So, you'll make right about the same boost it looks like. But you're going to go from 10 to, you know, 20 25 versus 10 to 12.
>> Yeah.
>> Like it's going to be so rowdy on high.
And you're at 7,800 instead of 5800.
>> You know who we really need to talk about is Foster Pell.
I appreciate him supporting every video.
He always drops a like and a comment.
He's just a really good supporter of the YouTube channel. And I do appreciate it.
Foster all glazed up now.
>> Well, yeah, cuz he said, "Go make another YouTube video. Nobody's going to watch."
>> Yeah. Right.
>> So, we'll shout him out and be hassle.
>> I know. Oh, I'd be mad, too, if my calves didn't look like this after working out so much.
Guess I should probably pay attention to what Josh is saying. I think we're good.
Once you have it on the sand, send me a low boost and a high boost log.
>> Josh Higgins definitely got it figured out. He was quick. I mean, what we were 2 and 1/2 hours, start to finish. High boost, low boost, launch control.
>> Yeah, not even. I mean, we're not even 2 hours or an hour and 45 minutes from the time we left my house. drove the five minutes over here and then started tuning.
>> Yeah. So, that's that's not bad at all.
>> Yeah.
>> And then sensor calibration last night.
I think it was 30 minutes and half of that was my problems that I had to run through and fix. Highly recommend Josh Hagen. And I'm going to go home, load this car on the trailer, and I'm going to go to the dunes for the whole week.
Now, >> we'll be out for invasion. Be out there at least for the day for me. You're going to be there the whole week. So, keep it on low boost till at least Saturday. That's my thing.
Okay, I can I can do that. I think >> I've blown my car up before invasion started two years in a row now.
Just go straight through and then over the matter.
like going out and ripping like an absolute degenerate and rolling into the Maverick for a freshy. Yeah, we need some fresh we need some air conditioning is what we need.
>> The fresh water. What'd you get, Alex?
>> Got the ice cream, Sammy. I already ate most of it, though. It's hot out here.
>> Squeaky wags.
>> Sounds like Ricky's car rolling up to the scene, squeaking and squealing.
>> Poor Ricky. Poor Ricky.
Poor Ricky.
Another successful tune.
Ready to go to her new home.
Well, that was a successful trip. She didn't blow up. We have an intercooler fan that's ticking. And other than that, I think we're good. Go test it on the sand. See how it does.
>> You going to run her on the trailer tires of the dunes?
>> I think it'd be fun.
I don't know how much you're going to accomplish.
Oo, look at that pretty billet in there.
Oh yeah, we got to we got to shout out Jared.
He did send over a tank we're trying out. Looks like I overfilled the oil though. Look, we got that pink fluid in the diff.
>> We got the fancy stuff, huh?
>> Yeah.
>> Nice. And it's still pink. Yeah, that's always good.
>> Yeah, mine never stays pink for very long. It usually turns about gray and it's very magnetic.
