I just got rid of the cat,stock replacement muffler,and 2'' exhaust on my 22rte and replaced it with all 2.5'' with my old flowmaster. The rest of the truck is stock. Now instead of 7-8 psi,it's spooling really quick and creeping up to about 10psi+ (I'm letting off before it goes any higher). If I just put a manual boost controller on there,should I be able to get rid of the boost creep? If not,any other suggestions?

 

So it looks like maybe I have to port the wastegate hole on my turbo to get rid of the boost creep from what I've found? There's got to be someone on here that has had the same thing,or something close to it happen. I need to know what has worked.
