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

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.
