[@Gadzilla150394]

BTW we are still working on the tune as we speak, car already has a new Map sensor, new boost solenoids, new vacuum lines, everything has been checked 20x times, Tuner knows what he is doing with the N54 platform so I’m working with him to solve the issue.

[@48763405]

LOL My car is having the same issue: No code, over boosting, throttle closure. Please update once you guys figured it out.

[@48763405]

I think I found the culprit for my car....I left JB4 in stock flash (steering wheel control menu 4 option 3). I switched to menu 4 option 2 for Backend Flash, and then did 4-5 pulls, the problem seems gone as now. Hope this help.

[@SavageBunny1]

When I rebuilt my wastegates, I didn't leave enough clearance for them to move, so when they would get really hot, they would get jammed.

[@marklamberton541]

A temp fix would be install a standalone boost controller and set that to your target pressure to get it running safe for the meantime. If that doesn't stop your overboost, what size wastegates, internal or external? They may not be big enough to divert enough exhaust out and this could be causing your overboost.

[@marklamberton541]

Thinking about it if they are internally wastegated turbos it very well could be the issue. Ask your tuner to dial back fuel and see if that bring the boost down.

@VehicleVirals Did you delete your vacuum canisters? I had thottle closure issues due to slight overboosts since I removed my vacuum canisters. I'm gonna but them back on and I'm pretty sure this will fix the issue.

Yes I deleted them. I'll mention it to the tuner. Appreciate it!

[@JimHardee]

I am experiencing this same problem on my car with MMP1K turbos. Jake from Motiv is tuning my car and it's been giving him the same headache. I also removed my vacuum canisters and didn't even think about that may be causing the problem. I am going to put them back on right now.

[@Mpiantine]

Me: Mannnnnnnnn, I want one of these. Me at the end of the video: See, this is why I don't want one of these.

[@HPAddict]

I tune n54s and throttle closures are because of overboost. The torque curve is very ugly, so yeah, throttle closures going on. But if you posted your datalog I could help you. Most tuners don't even touch the PID though, if those tables are wrong, you get oscilations and post spool overboost. Poor Ali looking for an issue, but the only issue is in the tune. You could literally reduce wgdc base to 0 and have no boost, so you having an overboost with this new tune and not with the old tune is 100% not hardware related. End of story. Again, post a log and you can get more help.

[@VehicleVirals]

Well my previous tuner was experiencing throttle closure but since he had more time with the car he was resolving it which is why the tune was producing over 500HP. Aaly told me to tell you to dm him via Instagram @_mr_evolution_

[@chrisrobles2012]

Finally someone who understands !

[@snivesz32]

I think his PID tables need to be tuned for the bigger turbos. It makes sense that the ECU thinks they are stock and so a WGDC X produces Y boost but with bigger turbos X will produce 1.5Y. The ECU sees this as an overboost condition and uses the throttle to regulate it. That’s my theory without seeing logs yet.

[@ichoozjc]

@@VehicleVirals Don't you have to adjust the wastegates on ps2 turbos before you install them? Maybe they are setup wrong?

[@sachak]

Also a boost solenoid could be bust. It will pass the vacuum test and appear to be working under idling conditions but it causes throttle closure on boost due to a damaged diaphragm, disconnect the vacuum line that would usually go to the vacuum canister and suck on it and then block with your tongue if it doesn't hold that vacuum i.e. stick to your tongue or slowly lets go then the solenoid is bust. I have had this happen a few times and each time it caused over boost.

[@VehicleVirals]

Interesting.

[@adamsisneros8307]

i’m almost 100% sure you need to upgrade your tmap sensor which is located on the charge pipe in order to run higher boost. if it’s not upgraded and you’re trying to throw big boost at the car it can create throttle closure therefore limiting power

[@VehicleVirals]

Already upgraded.

[@Karim2clean]

It’s worth taking a look at how your wastegates arms are actuating. When I rebuilt my turbos I didn’t bother measuring when the wastegates opened and closed and it caused a bad overboost issue and even with wgdc adjustments i still got throttle closures. I’d recommend testing those wastegates, and seeing at what mmhg they close up. Another thing I’d suggest is getting those turbos examined, my ps2’s were a non stop headache. Got them rebuilt 3 times before I gave up and moved to a different brand. The stock twin setup just isn’t meant to be pushed like that. If you’re chasing power I recommend you go single turbo. So many of your headaches will disappear! Edit: on second thought I still think your issues are tune related. Those graphs looked ugly.

[@jhssrg_lfdesrk]

Bro I just fixed that same issue on my car 2 days ago!! Those boost solenoids your guy was looking at do not fail immediately, they fail by over boosting for some reason. I had over boosting for a while and just replaced those boost solenoids. 100% will fix the issue. Easy swap!

[@leotomassetti8434]

Hi Christian, i have a question, once you flashed xhp on your car and then upgraded the turbos and tuned the car did you do something to the xhp tune or you left it as it was before the tuning? I mean if xhp needs to adapt to the new power output

[@reecewhiteman6723]

Does your car have an upgraded map sensor? Because the stock sensor can only read up to 22 psi accurately and with upgraded turbos you are going to be way beyond that. If you haven’t upgraded the sensor this might be your problem.

[@Timilias]

Couple of points: 1. You can always try to swap the map to the one from other tuner. If that map is not having issues with throttle closure, its the tuner problem, not the car; 2. If you're after 600whp from pure's on N54 you may well be dissapointed. B58 Pure 800 is rated at 800 and highest I've seen was 760whp on e80+meth and that was a kill map, not a daily map. You're running out of the turbo efficiency range. I dont know what are typical N54 pure results, but I imagine its not >600whp :D. Either way, I feel ya. My car has been similiar - timings pulls for no reason. Dynoing consistently 10-15% lower than it should. At the end it was the tune in part and in other part still my car acting up.
