I have been trying to chase down a problem for a couple of months now and I am about out of ideas. My car is not boosting over about 10lbs, but as soon as I go WOT it pegs the knock guage. I have replaced the computer, the battery, the MAF, i've redone the grounds at the back of the head, and redone all of the fusible links, and checked for wastgate puck alignment. I just dont know where to go from here. If you have any ideas let me know.
