HELP CORRADO G60 Turbo RUNNING LEAN

[ShooterMcGavin]

so heres the car
g60 42lb injectors.
stock FPR SNS Stage 5 tuning for 20psi,
garret turbo .48ar .50comp.

cars been running really lean lately i feel a lose of power and resistance in the gas pedal.

pulled my fuel pump saw the screen on the bottom was completly covered so i got a new fuel pump from TRE. changed the fuel filter. and got a new stock fuel pressure regulator.

after all of this its still running lean, to the point where im about to get new injectors. any help?

There could be a number of issues.

Bad Digi
Bad injectors
Bad fuel pressure regulator
Insufficient fuel flow
Too small of an injector
Vacuum leak
Intake leak
Bad o2 sensors

Best thing to do is break out the Bentley and go to town.

one thing that sucks with chips is that you can't easily alter fuel injector pulse width. this is why standalone is so nice. id max those babies out

3.5 bar FPR

you think i should upgrade to the porsche 3.5 for some extra fueling
?? i been running the stock FPR for like two years now an its been doing good while i was running 14psi... i have kicked it up to 20 in the last month.... all was well till i clogged my fuel pump and now i cant seem to get the appropriate amount of fuel now.

yea thats what i heard, basically reads it to 15psi then goes static and dumps fuel..so what you think mega squirt? for some better tuning
