Purchasing LS1 edit for my 99 C5
How do you go about tuning your PCM?
What do you change?
I have the following installed on my C5:
Halltech Intake
TTS Powerloader
TTS Headers
Bassani X-pipe
B&B PRT's
stock cats & option to remove them and add my test pipes.
NX wet system
My question is can you have two programs?
So that when I'm at the track and want to run w/o N20 I can have my Naturally Aspirated program.
