Can’t go past 4k rpm’s unless low throttle

Hey guys,

I have a gen 1 MS3 and it’s having an issue where it’s not going past 4k RPM’s unless I’m very light on the throttle..

NGK 1-step colder Spark Plugs Gap .24


I can’t seem to figure it out. I just replaced the throttle body thinking maybe that was it and I recently got new plugs. This build has less than 10k miles on it. I’ve boost leak tested multiple times. When it’s hitting that 4k RPMS, I can hear my turbo spooling, but I’m just not getting any power from it.. any help is greatly
appreciated. Car has been down for a couple months now.

Thanks in advance.

I hope that spark plug gap is a typo because it should be 0.026-.028" (tighter down to 0.024" as per tuner usually) not .24

Who's your tuner? Have you talked to them about it? Have you taken a log of the issue? That'll help us help you

 

You say that you have 10 k miles on the build. Have you changed anything recently

 

PD Tuning. Will Dawson. I’ve talked to him about it. I gotta get a log of it happening, I just don’t want to damage anything in the process either. I’ll definitely get a log though and send it his way and post it here.

Also, I meant .024 my bad

Everything is pretty new. But I’ve never been able to drive my car 100% properly. I keep breaking stuff. I just replaced my clutch pedal assembly, cuz it broke.

 

Here’s a couple logs.. #1 is just bucking, won’t go much past 4k rpm’s.. I tried to be on the gas, but bucks make it hard. #2 is having clutch all the way in, and barely moving, car idles up and down and dies.

 

Boost leak tested?

 

Yes, multiple times. Very very little air leaking. Hard to fix as well. Car has been running fine with it since the beginning..

 

Any update on this? I'm having the same issue
