I'll get in contact with uprev Monday/Tuesday time frame.

When I tune, I always disable the ARC stuff until I'm done, then I'll reflash the ARC license, and give her a drive around the block for a sanity check.

Basically what this car is doing, once it reached the flat foot shifting RPM/rolling anti lag RPM, it would basically cut power. I currently had to turn everything off, with the exception of Launch Control.

One other issue I'm randomly having, is I can't turn off or on toggles for the DTC. Are you having that issue too??
