I have stage 0 pcm and I have and AGP wastegate and stage 2 injectors on my car and i tried to turn up the boost past 15psi and the pcm just cuts power when it goes past 15psi of boost. I am getting a diablosport in about a month but i am wondering if theres anything I can do to get it to hold over 15psi untill I get it. I heard about disconnecting the red vacuum line and capping it off but it didn't work so idk wat to do.

 

I don't think there's anything you can do without a stage 1 pcm other than the diablosport. At one time, I ran mine at 17 to 18 psi with kinetic wastegate, but to be on the safe side, I turned it back down. This was without the stage 1 pcm...I have an 04 SRT-4, mostly stock. At this time, I'm mostly running stock and I took the kinetic wastegate back off and reinstalled the stock...gave me more ease of mind, than to mess with the boost.

 

Sorry, I sent this to the another section for replys. I tried to cancel but it didn't work.
