ok well ive done a search and cant quite find what im looking for. i have a d16 z6 with mild bolt on mods...i m, throttle body, header, 2.5" exhaust, fpr, and fuel rail. i made the mistake of driving without knowing the fuel pressure and finally got around to buying a gauge. it was about 60psi so i turned it down to stock specs around 47psi (hose removed) and it runs like complete ****....it chokes up like it wants to stall. do you think i now have a bad o2 sensor or am i leaning out?

 

I suppose with your list mods you should have alot more air going in and out so you may need to raise fuel pressure to compensate, but the best idea is to get a air to fuel gauge, then you'll know for sure if your leaning out or not

If it's a wideband, otherwise you just get a pretty lightshow...
