    LTFT problem

    Looking for help. My LTFT is always -4.7 even after 5 adjustments to the MAF frequencies. Mods are FAST intake. Custom headers and intake. I'm doing a MAF tune first and just mapping from 2000-4000 rpm. PE turned off. E67 ecu. Don't know what else is happening.

    I'm currently in the same boat. on the dyno.
    LTFT values are higher. then about 20-30 seconds after start up, the LTFT values drop to %-4.7, and stay there.
    ID850 injectors, rescaled according to Injector Dynamic's values, 2013 CTSV.
