I have a 2001 Monte carlo SS and I purchased a Hypertech Power Programmer 3 to tune my ECM. I have never done this and I don't want to ruin my car so does anyone have suggestions about where to set everything for MAXIMUM performance without damage. I have 22" wheels if that makes a difference...

Waiting on Gen8...

 

i had a hypertech programmer and i didnt notice a difference once i installed it and messed with the tables it offers. if i were you i would return it.

22" wheels kills all performance anyway, if you want performance take the huge rims off to start.
