    +1. I have one on mine, but its really only because 1) I was given it and 2) It was engine dress up. I set mine to factory. Isn't setting it higher than stock, make it run a little crappy? I believe it makes you have more soot and such tho too because more isn't breaking it completely down. But correct me if I'm wrong. -Gary

    adjusting the pressure higher would make the car run rich.. use more gas and spit black smoke out the exhaust depending on how high the fuel pressure is set.. it also causes it to bog down really bad when taking off
