Just want to compare pressure under WO throttle. Mine is messed up I think. As soon as I go WO, the pressure pegs at over 100! Then after a few seconds it slowly falls back to about 70 psi. The car hardly pulls at 100, put steadily pulls harder and harder until it hits 70, where it is pulling like crazy. I know something is wrong with it, but it has just gotten pretty bad the last few weeks, and prompted me to do something about it. I have already taken apart the FMU and all seems good that I can see. Any help would be great.
