Basically, I have a ct26, commonly found on all tracs, gt4, and mr2's. I want to lower the stock 7psi to 5psi. You can mod the wastegate arm by making it longer, it will open sooner, because of pretension is greater. How should I go about making that adjustable? I cant think of a coupler that would be suitable because if i cut the arm, thread it and put it in the coupler, wouldnt it be threaded weird so it cant be adjustable?

eh what to do?
