Ok I cannot sleep at night! I cannot figure out why I am experiencing so much knock! Besides the mods in my signature, I have replaced the spark plugs/wires and a new pcv valve. I also have a new fuel pressure regulator and thrasher 92 chip to install. The wierd thing is the fact that I experience approx 3 knock at about 55 mph and 3000 RPMs right before it wants to go into overdrive, but no boost? Also, the knock fluctuates alot on different runs, expecially as the engine heats up. Its usually about 6 knock at 10 psi.
