fit a ajustable boost bleed of valve in the hose between the waste gate servo and turbo housing then turn the screw out for more boost in for less. these valves are avialable from any performance parts store go for a manual one as their cheaper and more reliable than electronic ones

they run the car on the dyno and tune your computer or engine management to 10psi or more then changeing the turbo settings through the standed boost controller with the turbo
