hey i just want to know how to increase and decrease the boost for a internal wastegate. do i length the wastegate for more boost or shorten it for more boost. also you know that thing that the wastegate pushes on at the end(that thing that flaps open and close on the exhaust side of the turbine), when it is close, does it mean that the turbo is at full boost and when it is open, the turbo is not on boost? i hope you guys understand me. my turbo kit will be put in together by tommarrow and i just want to know before i start up the car. let me know asap.
