I wanted to know if there were any files out there with a decent tune for the 5.3 / 4l60e combo. my buddy started playing around with my truck with HPT and he is still in the learning curve of it and i just want a tune .
does anyone have any good tunes they would like to share?
thanks

try loging in and then filling out the info in the tune repository

 

My tune for my 5.3/ auto is in the HPT repository. Its pretty good 93 octain only though.

then go to the repository, he can login from there with his customer info and get all kinds of tunes.
