it will go all the way to 50ish but does more harm than good, its best to wastegate them at or around 32-35psi

I was boosting around 56 psi. which was stupid on my part for doing it. I think thay can start coming apart around 40-45 psi. dont quote me on that, but it some where around there. I had wastegate plugged off with 100hp injectors, 10 plate, .093 lines, timing 16. 3k springs.
