I know and Ive been very patient with them trust me it just seems like from the time they answer after waiting an hour on hold they just want to hang up and ask the most rediculous questions almost like they're mocking me which they probably are. Anyway I'm going to figure it out myself. So can anyone help me out with a schematics diagram of the data bus link and all modules so I can start testing for shorts? It has to be 2002 Chevy suburban vinz made in Mexico specific from my understanding from the research I've done so far.

 

www.jannettyracing.com. This guy Ted Jannetty is an LT tuning guru that also sells SCT's with tunes loaded or he will put a tune on your's. Pretty certain he does LS too. Personally I would just start over with an HP Tuners tune (Atomic) as RedXRay said but this guy may be able to help you with your SCT contraption. Good luck
