I just put in my MBC and I cant get the boost down. I installed it correctly. When you unscrew the knob it is supposed to set the boost at a low level. I was hitting 9-10psi and I was letting off because I dont want to blow my engine. I think it would go higher but I was letting off the gas.

I got it working right. I just had the screw too far out and it wasnt putting and pressure on the wastegate. I screwed it in a little and now I am running 8psi!!!!!!! What a difference from 5-6 psi. I LOVE BOOST!!!!!!!!!!!
