Re: SL55 Fuel Pump Fact, Fiction or Matter of Opinion?
I’m approaching 40k, however the filter/regulator was changed 1yr ago, same problem before the OEM replacement. You’re not going to see the lean condition on a dyno no matter what. I never ran lean on the dyno and I have done 12 pulls. The reason is you’re getting significantly less air flow on a dyno.
The NW solution is interesting but requires too much “additional” hardware and a half/ half tune to correct the bottom end a/f. Does anyone know what size injectors we have? Anyone every had them flow tested? How do you measure duty cycle on a datalogger?
The gentlemen at the Dallas Tune Date had 48lb injectors and an SL55 Fuel Pump, WAY TO MUCH injector for what we need. That’s why he runs rich on the dyno and on the street.

Reason: Injector size is 48lbs and not 44lbs
