when accelerating to highway speed my boost fluctuates from 18psi to 10 back to 18 and so on. I am running an adjustable actuator only. do I need to adjust it alittle to hold the wastegate closed more tightly?
check you're hoses for any kinks. mine did that had to reroute the hoses.
Tighten it more tightly, and use a manual boost controller.
I'll see what I can do with it when it cools down a bit more. will keep you posted and thanks again shawn
