    Nitrous Tune Help

    Still seems to me to be running a little rich. Any help to improve this tune is appreciated. Should LTFT lock in at 0 when going into PE? Is this why my actual AFR is so much lower than commanded?
    Thanks

    You need your trims in cruise to be spot on. Any active trims are carried into your PE mode.

    In PE your adding fuel in the ADD vs RPM chart. Is this intentional?
