Alright, I have a 2001 Silverado that was originally a 4.8. The vehicle now has an LQ4, and will soon be getting a turbo kit. The PCM is a P01 with an 8322 OS. This truck is also getting a 4l80 swap. My question, if I find a tune in the repository with the 156 OS that has 3 bar upgrades, and is also a 6,0/4l80, will that take care of my 4l80e segment swap that I will need to do anyways? Thank you, this site is awesome.
