My shop just bought the SCT tunning for GM, we also have it for ford. So any ways if i tune my PCM at 5 lbs of boost and use my boost controler to hit 15 lbs will my PCM adjust, Or do i need to tune it at 15 lbs. I am just wondering how you guys are setting up your tunes for multiple boost levels. Thanks for any help.

 

is anybody on here that is doing their own tunes that can help?

 

if you are going to run a max of 15 psi, then you need to tune for the 15psi.

 

i agree, tune for max boost .
