FPS Psi is off = runnin lean

I'm havin a fuel issue rite now. I have an Adjustable FPS. I have it set at 35psi. Is this not enough for a DOHC ZC with header, gutted cat, exhaust and intake? Cause sometimes like if I idle for awhile and then give it gas it will blow out a little greyish/white puff and it smells a little like gas. My friend said that I mite not be gettin enough fuel and I should raise the PSI a little.

1st of all what is a FPS? I am assuming you are talking about the FPR. 35 psi of fuel with the vacuum line off/WOT seems too little, raise it up at 40-44psi. I have my D16a6 set at 45 psi and I have no prob.

Lol, FPS. I dunno what I was thinking, it was like 4am. Yeah I meant FPR, so you say around 45 is okay. I'll play around with it in a minute and see i guess.

make sure it is tuned with the fuel pressure vacuum hose off.
