Oh yeah, and ready to go back up with it. Had a stuck lifter on #7 cylinder , I guess this AFM systm is hard on them. I almost started o do a complete DOD delete on it. It is my grandson's truck he JUST bought and had this running problem and a tune didn't fix it. He is in a rush for it, I got a hold of the dealer he bought it at and they were helpful and gave me the head bolt torgue specs. They were 1. 59 ft lb then 90degree and 60degree final torque. It has been an experience not like the older cars .

I have a 2015 GMC Sierra 5.3 C engine; replacing some lifters and need to know the head bolt touque specifications. Can anyone help?
