Power loss at WOT (under hard acceleration) any help would be appreciated

Hello all,

I have a 2015 DCT M3, currently running stage 2 ECUTEK FBO E85.

At wide open throttle, the car cuts power completely, it's like hitting a wall. The engine does not shut off it just loses power.

Has anyone had this happen to them? No CEL or anything. I do a hard pull from 2nd gear and near the end of the gear it cuts power. Happens in 3rd too. Only when flooring.

My tuner is trying to figure out but thought I'd ask here too.
