Kind of a shot in the dark here, don't think ss silverados came on 07... But I have a 07 silverado classic single cab I cloned... All cladding 14 bolt rear and 4l65 trans.. 4.8 engine that I installed a turbo kit with 60lbs injectors a two bar map sensor etc... The guy I have tuning it is having a problem with getting the tune right... Anybody have experience and could help? He's using hp tuners software
