#11100, "Fuel pressure level" In response to Reply # 0
I just got my fuel pressure gauge installed today and my fuel pressure is 44 at idle, is that about right? I cant do any boost runs till I get the gaskets in the mail from hahn that i need. -- Brad Rickard 98 GS HRC Stage V (nuff said)

You shouldn't need a FPR after intake/header/exhaust. NA our cars usually run rich. Most people use an AFC to lean things down instead of adding more fuel. Get a numeric A/F and you can see how rich your car is running (or lean).

Darkone said he had 1.6v on his.
I was in 2nd gear and slowed way down and floored it in second at like 10 mph. It got really rich until 3000 rpms or so. At WOT I hit between .92 - .98 but it's never the same for certain gears and rpms. I guess that shows you how fast the computer is changing the fuel injectors. I know I am running a little rich and should probably lean it out a little bit with a S-AFC.

Super20G mentioned the right range...but it really depends on your car and installation. Bad wiring or a bad ground can make alot of difference. Getting 1.04V once isn't bad, the O2 sensor tops out around 1V (+/-?). If you got 1.2V+, I would be suspicious. One test is to get going about 40-50 mph and quickly pull your foot off the gas. The A/F meter should hit approximately zero. If it is significantly negative or significantly positive, you have a problem. We're talking numbers on the order of 0.05.
