Can anyone show me a screenshot f the tables or just shoot me a stock GMC file

 

would a chevy file work, im still new to this tuning thing. i have hptuners for 03

 

i dont think so they are locked very specifically for the trucks

 

A Chevy file should work ... be more specific for what you need.

I have an 02 5.3 and a 03 5.3, if it's a 5.3 I can hook you up, otherwise, you will need to find the right motor.

If you will give me your email addy I will send you a stock 03 5.3 file.

 

i cant view chevy 03 with my hptuners, can you take a screenshot
