    Default L99 won't run with MAF enabled

    I added a TorqStorm supercharger to my 6.0 running a L99 OS on E85 and after shutting off the MAF to tune the VVE the engine will not run or idle with the MAF reenabled. If I unplug or turn off the MAF in the tune the engine will run and idle fine. I tried another new Hitachi brand MAF with the same results.

    The MAF frequency and intake air temp both have good realistic data in the data log so I have a hard time believing both the MAF sensors are bad but I'll return the new one under warranty and try again.

    I shut off the MAF/ MAP/ throttle pedal correlations/ performance checks thinking that the supercharger was exceeding what they were stock and causing the issue.

    Attached is the engine file, any help is greatly appreciated.
