how i can make more boost on my lbz ?

i have ppe at stage 4 but i whant more boost? tanks

PPE makes a boost controller that is adjustable using a dial. I have seen as much as 40 psi, by accident. I only use mine when I tow heavy to keep EGT's down.

How much are you seeing now?

I keep it unpluged now unless I tow. No matter how the toggle switch is it will go past 40 psi with the dial turned all the way to the left which should be the lowest setting. It works for me just fine because I only use it to cool the EGT's when towing heavy, with a heavy load I keep it under half throttle anyway so my boost does'nt get too high. When running empty I get 32psi without the controller so I figure I dont need it for performance. Does it sound like something is wrong with my controller?

How much are you seeing now?
