I have been reading about fuel injectors and is seems that the fuel pressure standard is 3 bar which is about 43-44 pounds. The recommendation from Tracy is about 35 pounds. That will reduce the flow of the injectors by around 11% or so. Can someone (hopefully Tracy so it will be a fact and not a guess.. :>)) shed some light on why we are at a lower fuel pressure? What pressure does the car run at? Bill B
