prostitution for TR parts
Are all 38mm wastegate springs the same size or are they specific to the wastegate? I have a turbonetics evolution 38mm wastegate, and the heaviest spring it comes with will only give me 10psi w/o a controller and 15psi with the controller. If I adjust the controller any higher than 15psi the boost jumps around and starts to blow off prematurely. BTW, a stock wastegate would give about 23psi, but I changed DP's.
