any idea what the average gain on my truck would be if i put a sts turbo on my truck? keep in mind that it is a 6.0 and is and 4x4.

 

Depends on how much boost, size of turbo and other supporting mods (FMIC, cam, meth...). On average, 100 rwhp for 6-7 psi. Would be more with the previously listed mods to go with. I added 200 rwhp with my STS on a 5.3 and 10 psi with a FMIC, cam, meth and fuel support.
