hey guys, installed an intercooler and boost controller a while back, now the boost controller is a manual one with a little screw to wind in and out with a wire running into the cab where i have a little aircraft flip switch for high low boost, i took it to the dyno the other day and wound the boost to 9psi and got 298rw/hp then wound it to 10psi and got 307rw/hp. i was aiming for 320 so i tried to wind it up more but nothing happened. after 10psi it didnt matter how much i wound the screw out it would sit on 10psi sometimes hitting 10.5psi.
whats goin on i want to push 12psi. getting very frusturated. is it the controller or turbo? i dunno
