High fuel pressure..

[TT/Ameasap]

My 02 readings have been lean ranging from 720-780 I have thrasher 92 chip and it calls for 45psi line off. I have a cheap fuel pressure gauge and line off it reads 52psi Can the FPG be off that much? or is it 02 sensor? Because all was well before and now all of a sudden this lean cond. has occured

I really want to know if I can bump fuel pressure even higher to see if 02's raise with out hurting anything to see if it is the FPG thats funny Is that OK?

I had the same problems, turned out to be my regulator was bad.

Did you get the FPR rebuilt or do you have to buy a new one?

Well, I was just out after bumping the pressure a little and now 02 are looking good! 780-820 range hmmmmmm... I guess I will leave it there until somthing tells me otherwise. oh,I did forget to mention that I removed a MAF screen. I wonder if that cause this lean cond.

Anyway thanks Kevin,
