What does your fuel pressure do under WOT N/A and on the squeeze? Do you have a fuel pressure gauge?
Maybe get a test a/f gauge from the auto parts store. It just screws onto the fitting at the end of the rail. then you would know wether your gauge is good or bad. Less than 10psi of drop really is not that bad, if the nitrous tune is set to comprimise. Myself, I like zero pressure drop and we can set them up this way.

I may do that. I was thinking about it anyway. The fuel pressure gauge was normal on the ride home after beating on the car today at the track. Go figure!

This just started happening. Is that alright? I have the racetronix upgraded fuel pump. This never used to happen and I can't pinpoint what's causing it.
I'm worried that when I spray my nitrous it'll be more of an issue.
Any help or guidance would be greatly appreciated.
Thanx
