    So on my setup I already scaled the 60lb injectors back 30% for e85 and I have a ls2 maf. Im hitting aprox 10,875hz on the table occasionally so I dont need a maf scaler yet. Tuning has gone well so far and I have everything below 7500hz locked in at 2% or less. My issues are with 7500hz+ because im maxing out the table at 67ish lbs. Im guessing taking the injectors down another 20% and then taking the maf table down another 20% will take care of it but I just wanted to make sure.

    Something is wrong. You should be able to use a stock LS2 maf table, which doesnt even pretend to max out. If you are tuning the maf at all there is a mechanical issue, I have never needed to tune a LQ4, LT1, or a stock maf car's maf table before.

    When I switched from stock maf which was nearly perfect to ls2 maf and table everything was off by 15+ percent wideband and narrowband. No way just changing the maf caused my entire fuel system to shift 15%.

    Figure out whats wrong then. I usually just start with a stock tune, then dial the injectors in where they need to be on a stock maf table.

    You've got issues. No way your MAF table is even close to correct. Go back to your stock table, and check everything over.

    scaled injectors, then your maf table magically added 50%?
