does anyone have any idea why there is like a slight knocking sound when i shift gear while driving my car? its a supra. but if i step really hard on the clutch, i mean step till the end then no sound. pls advise. thank you all very much
Yesterday while testing car at the highway I'd dail up my boost a notch higher to 1.0bar. I normally run on 0.8-0.9bar.... but just want to test higher pressure for a while.
