I failed the tail pipe sniffer (actually was only a pretest for smog). Had too much HC and too much CO. That usually accounts for too much gas. And it's true. I was getting CRAPPY gas mileage at the time (about 19 mpg). I fixed a few things, and now i'm getting about 25mpg. But, I am getting an adjustable FPR in a few days.
My question: I was wondering what is the lowest I can set the fuel pressure to and still be safe (I know if I put it too low, the NO will go up-but I'm pretty sure I'm still running VERY rich)? This is on a bone stock b16a with cold air intake btw. Oh, and this is only temporary so that I can pass smog.

Anyway, I'm gonna need a fuel pressure guage too. Where can I get one for cheap? Thanx!

 

the B&M FP gauge is like $25. Once you lower your FP below ~30 psi, the motor starts to miss and pop.
