Running higher fuel pressure

He will if he uses the same dyno he used last time.
I'll make sure I get uncorrected #'s this time as well.
So no one agrees with the better atomization of fuel with higher fuel pressure? Looks like I need to turn it down and run stock base pressure.
Scott-
I know, I'm just saying that if you are going to the same dyno, you barely need anything else.
If you are going to a different dyno, then that's a lot to wish for from pump.
Have been on 3 different dynos at this point (4th one next Tues). All have yielded similar results with the Mustang being the lowest.
So I'm going in for a tune next Tues (hopefully for the last time this year after a summer plagued with issues). My buddies tuner (tunes mostly EVO's) told me that running a higher than stock fuel pressure will result in better atomization of fuel.
Right now I'm at ~58psi at idle, but am willing to change that when I get to the tuners next week (if it's set too high)
Will probably be looking for ~550hp (corrected)
Full-Race kit w/GT35R
Ported and Polished built head (OEM HG, ARP studs)
ID1000's
AEM S2K fuel rail w/100psi pressure gauge
AEM FPR
Aeromotive 340lph in tank pump rewired off the battery
Hondata K-Pro
91 octane pump gas
Will be pushing between 13-17lbs of boost (guesstimate)
So do I need to lower my pressure? Any disadvantages to running it where I'm at?
