I have a Super Duty, intercooled set up in my truck and the wastegate seems to be out of adjustment. When its attached it will push 13-14psi during mild driving and about 18psi full throttle. When I block off the wastegate it will push a max 26-27psi but is very fluctuating. I feel like when its on its not enough boost and when its off its not a very controllable amount of boost. Can someone help me out here? Thanks
Unhook the wastegate rod and turn the end. It's a threaded rod so turn the end to adjust it. You can stick a mighty vac on the wastegate and pump it to see when the wastegate starts to open up and adjust it to your liking.
