The car runs fine just driving around town but at wot i cant get the car to rev over 4000 with out getting bad knock. I even tryed to run cam2 and unhook the knock sensor and it in park but it will rev to 4800 then falls on its face. My y link reads crazy at wot, 13 volts, 6 volts , 0.3 volts this is when i get the knock, alt tested good, batt good , belt good, . Ive tryed to change some parts and still does it. Ive tryed my brother coil , plug wires , plugs gaped at .34 , tps .42 -4.66 wot . I even pulled my valve cover to make sure i was getting oil to the lifters and cam was ok. I have tryed 3 chips and nothing.
cam sensor is on, what would make this thing not rev over 4000 when under boost. Iam also running 780-800 on the o2's and at 14 psi.
any help would be great , thanks guys
