Is there any way i can make my waste gate hold out longer before ingauging.

 

Boost Tube

I have this on my truck it claims to keep the wastegate closed longer and build more boost but to be honest i haven't noticed a whole lotta difference. That's the only way ive looked into but someone else may have other ways of achieving this.

 

adjust the rod. applying shop air slowly up from 20psi to what ever you want. adjusting the rod tighter

thats how i did it with my 38r. made about 37-38psi of boost at high elevation

 

ok, thanks
