    2021 Mach1 with P1X hitting ETC FMEM

    Car won't rev above 4900. Stumbles and hits ETC FMEM. Was in process of dialing in MAF when this happened. Air Load showed 2.1 and my Air Mass Max was 1.85 so that may be my issue. Have not started back up today on dyno but wanted to post the last tune and log to get some feedback on possible issue/clip I'm hitting.

    list your mods

    fuel injectors
    fuel system
    pulley size

    hitting above 2 in load is either your running crazy boost or your injector setup is wrong

    Nothing was way off. I did make some minor MAF adjustments but the clip I was hitting was In Eng Diag tab under Airflow, there was a Max Load table I needed to bump up the max load a bit in upper RPM. Car dialed if fine after that and made good numbers. Thanks to all who chimed in! Car runs great now, very pleased with results!

    He's right - your MAF curve is all over the place, this tune is just bad. No your car is not running great with a tune like this...
