my car is a 02 z28 with an A4 3,23 gears. my only mods are LMII and flopac and a larger y pipe. Im am wondering what my car in OD really shifts at when i floor it. When does the computer in my car shift gears.if if shifts at too low of an rpm would it help if i raised my shift points eventhough my car is stock. im intrested becaus i can find a good Programer for cheap and wondering if changing the shift points will benifit my car.
if i can change my shift points at what rpm does the stock motor stop making power?
i hope i made my question clear

 

so no one has any info for me?

 

Heres a TTT for ya. I have a friend thats seen a gain with doing so. How much did he raise em, I have no clue, but hes pretty damn close to 12.0 with a bolt on and stalled full weight formula.
