wow! my fp has to be at 55psi to give me a decent a/f ratio on my aem wideband (WIDEBAND NOT NARROW BAND) thats with the vac line ON... my a/f is 12.7 13.0 at 14psi. 12.5 a/f at 10psi.... wierd, can't figure out why either, (I know thats not normal) tried swapping out injectors, fuel rail, ecu, wireing harrness, and 02 sensor... all had no effect. so i bought a fpr and turned up the fuel pressure. at 43psi vac line on, my a/f was in the high 13's witch to me is lean as hell... so i turned up the fuel pressure to 53psi vac line on.... I know it's not good for the injectors, luckly i only drive it on sundays, and will be upgrading my hole fuel package soon... I am under the impression the motor and turbo are stock, but I can't figure out where all this extra air is coming from... the motor had a adjustable wga on it and a piggy back of some sort when i got it.... So the guy was a tunner. only thing i can think of is maybe a clipped turbo i dunno..... car feels strong for what it is. guess a dyno is the only way to find out.
