My old cummins I bought a elbow and a BD waste gate for my truck and it would hit 45 w o problems I have this truck and have a banks waste gate and elbow and i don't see over 30psi and i have the banks turn up as much as i can with being able to put it back on the arm of the Turbo now Idk if because I had the turn buckle on the BD waste gate allowed me to tighten it more cause u wouldn't have to take the arm off to adjust it or what any ideas? Or does banks just suck as always
