boost controller help.

I installed Joe P MBC according to instruction.

1. Turbo elbow- controller
2. wastegate- controller

and use the adjustable bolt to adjust boost.

However, I am only boosting 7-8 PSI MAX no matter which way I move it.

dont know what I did wrong, if anyone else has had this problem?




note: plugged up all openings of solenoid

its Joe P XZ MBC

Ive tried switching the lines already and tightened the bolt to the max and still get the same (7psi constant). Even less when I loosen it (5-7max). Is wastegate stuck open?

Also make sure you are running 91+ gas. If you have the stock cat on than that may also cause a restriction.

it is running stock cat, but i actually LOST pressure. In fact it doesnt boost over 6psi at all, WOT or any gear whatsoever....dont see any vacuum leaks, double checked installation, checked all hoses, reinstalled...dont see whats going on.

Anyone in the LA area help me check see what im doing wrong. Maybe sometime this weekend? :)

Thanks
