It's opening, man. I've adjusted it already. It releases a lot of air. I feel it with my hand. When I put my hand on the compressor inlet, and let the throttle go, it'll suck harder for that moment. I don't feel ANY air coming out. I put a piece of paper on it with a screen and the paper got sucked harder once I let off the throttle. I don't get it. Why does it make a purging sound if it's sucking air and not letting it out? If it was the bad surge, don't you think that the turbo would've been dead by now? 4 years at 15 PSI should be plenty of punishment for a compressor surging. It should be broken by now...hell...long time ago. I don't understand.
