I was considering ordering the Stage 1 kit from modernperformance mainly to rid my car of any potential cel's...and I was wondering...Is it possible just to install the stage 1 pcm and later on install the injectors? I don't plan on doing any fuel mods any time soon but I need the Stage 1 PCM, will this work? Thanks.

Nevermind, I found the answer on srtforums. :screwy:

you have an 05. stage 1 is just a comp, no injectors.

Yeah I was being retarded and forgot I had s1 injectors :disappoin

can anyone tell me the boost on stage 2 upgrade

the turbo efficency tops out at 18psi at redline. you can spike 21-22 but anything more than 18 at redline creates so much heat that unless you have water injection and a big intercooler its not worth it.
