I have a 2004.5 3500 all stock but afe intake and aftermarket exhaust. A while back I floored it to get into traffic and heard a big whoose and then what sounded like a air leak checked all boots and everything was fine but power way down and milage was about 12 mpg. I replaced my wastegat acuator with a bd performance since I cant find a stock replacement, and was stuck took 70 psi to get it to move with an air compressor, helped but still not fixed. Does anyone have any ideas on what else to do?
