Just curious, hwo do you figure that?the MAP doesn't even see + pressure so it won't know what to do with that extra air. Granted Leon has a 95, but his fuel pump isn't going o raise fuel pressure, he stil has the stock reg on that will set it at around 47-50psi.
You need that extra 15+psi of fuel pressure to basically "push" more fuel through your injectors at eh higher feul pressure.
I think you might have it backwards. I wouldn't be afraid of boosting 3-4psi with a stock FUEL PUMP, and a 12:1 riser but not just a fuel pump. I'm not totally sure, but I know our pumps have top be good for at least 80-85psi of fuel pressure (otherwise you would see a lot more problems with the DRY NOS setup guys)
just my 2 cents, give me your thoughts.
Oh, LEon. dod you get your e-mail? FMU is on its way!
