90 Pontiac Grand Prix LG5 3.1 turbo v6.
Does anyone know where to buy a PCM tha is tuned for and controls to higher boost?
I read the car has about 7 PSI from the turbo.
Lets say I wanted 10 PSI, I can mechanically set this with a valve, but the computer will not like it as its programmed to provide fuel given the controlled boost
I know what I want to do, I just cant seem to find anyone who can program these cars on a dyno, and I cant find anyone who has done this before.
Cleveland/Akron ohio area, if anyone knows a place within a reasonable distance, I would like to dyno tune a PROM chip for increased boost.
