what factory tune do i start with? 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 on and i dont remember what i adjusted last. what factory tune should i put back in it to start over?
I would start with an '02 5.3L truck cal, and copy LS6 injector data in it to start with.
Every time you make a change, be sure to save that version with a different file name reflecting what you changed in that one.

I double checked all of my stuff and my injectors are from a 2000 camaro, and the 5.3 and computer are from a 2003 tahoe, anyways. 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?
The '02 motor is DBC and the '03 PCM is DBW. Not all 03+ PCMs can be used in DBC engines since some don't have IAC drivers.
You need to open yours and check it.
