b16a2

ive got the B&M FPR and its running at like 48psi and 50+ when unpluged

my air/fuel gauge stays way red and way lean until about 3k rpm's..

stock psi is what? around 38?

 

If you turn down the fuel pressure wont you lean it out even more? Is the motor stock? What ecu? What mods to the motor if any?

 

No you can adjust it either way

i got it tuned awhile ago but just recently has it been running so high

im runnin 45 psi on my regulator... are you running a wideband gauge or just using a factory o2 sensor with a gauge?

 

factory

 

with a factory o2 sensor your gauge is not accurate. do a search about a/f ratio gauges and u will see that only the units with widebands are accurate.

 

understandable but it works enouph to know its running high now then what it was

and the way my air/fuel gauge looks, it runs way lean until 3k rpm
