I am only able to push 55psi at full throttle and I have a stock plate in the stock position (pump has been on the bench). I have checked everything multiple times for boost leaks, and I did have a couple. So I am at the end of my rope, its 116 out and I cant be playing around outside too long without passing out My egts are obviously high and the smoke does not clear up. Down low , like cruising on the freeway boost is where it ususally is and same half throttle. Besides that the truck runs awesome. With my last combo and a 160 pump I could hit 65 psi if I wanted to.

Any suggestions?

 

good to see you got your truck up and running again!
I can't offer you any advice on your problem though. maybe check the wastegate?
