Question on Fuel Pressure fluction
I have been havin issues with my nitrous cutting out so I installed a new Fuel Pressure gauge.
I am getting a good deal of fluctuations in FP. Sometimes it hovers around 55-60 and then it will dip in 30's while just cruising. How much is normal? On a few full throttle runs my pressure was good.
Also I took my FPSS off and made a 3rd gear burst( where had most problems with nitrous) while watching FP. Fuel pressure was 58-60 and Nitrous ran great.
What should I make of this?
P.S. Have FFS fuel system and new Walbro 255L intank pump.
418 RWHP, 550 on spray.
Thanks
