Your fuel pressure is way to high. get a good FP gauge, and turn your static FP sown to around 16-20 psi it all depends on the car as to where the sweet spot is. (the bleeder on top of the SFMU is used to lower FP). you also need to make sure your running the correct disk/ring combo in the SFMU, your also going to need to adjust the screws on the side of the sfmu to get the FP to top out at the correct amount, and not keep raising your FP and such. your just running way to high of a FP right now. how is your fuel system setup other than the 450's, 255, and sfmu?
