I have a 2002 5.3 engine with ls6 intake and ls6 injectors, still using 5.3 maf and 5.3 throttle body, 5.3 computer installed in my 92 camaro. Anyways I'm needing to start over on my tune because i dont remember where i left off and i dont remember what i adjusted last. what factory tune should i put back in it to start over?

All cable tb parts? Id use a 02 Camaro or Truck OS 12212156 for it, one of the most versatile OSs available. Gives you the ability to run COS5 if you decide to down the road.

Grab a file off TuneFileDepot.com. :D

Yep, I just copied the # from TuneFileDepot really fast last night, that's the correct OS.

The VIN shouldnt matter, but you need to know if it is indeed an 03 PCM as they are 1MB vs 512kb and you have to use an 03/04 OS at that point.

Okay. also i double checked my injectors and they are out of a 2000 ls1. do i need to use that injector data on my 03 tune file?

i noticed in the comparison between the 5.3 injector and the camaro injector the "small pulsewitdth adjust" parameters are measured in different milliseconds. does this matter?
