will a 2 bar map sensor work with a s/c 99 ld9 cavalier?
If you're running the supercharger reflashed pcm from gm then you NEED to run the 2 bar sensor. That tune is unlocked and available in the repository on the HP Tuners website. Anyone with the program can download it and flash it onto your stock ld9 pcm.
