Fuel seems fine no leaning out

Dose it cut power violently
Because mine did it was fuel starvation even on a hard straight line pull
That's why I mentioned it

It does cut throttle pretty hard ... I have half a tank of fuel and haven’t had any issues before with less fuel .... but I’m not sure what fuel starvation acts like... and also this is happening on a straight away.... I also thought fuel starvation made the car cut off

Do you have a fuel pressure gauge? Your factory top hat could have broken. 1/2 a tank is about when everyone else with the issue noticed it.

I have a pressure gauge under the hood it’s reading same as when tuned ...
I still had the issue on the way to work ....on the way home eased into boost was smooth to about 11 lbs no issues ....tested it several times more aggressively each time no issue....get home reflashed the ECU since Jon suggested that one thing I noticed as I was getting out of the car was the window normally drops about 1/4 inch when the door opens ...well it would drop , then go back up and drop randomly with the door just open each time the display that says open door would come on and go off ....sooo I put up my laptop and cables started the car up idled fine ..revved fine ...2 step fine and window was normal ....

Yep mine would do it with that level of fuel on a hard enough pull
I and it was like a violent head but the wheel cut out for a split second and then the pump would pick up again

I have a second pump feeding the stock bucket now like z1s idea

Again not saying this is the issue but a simple one to rule out/test

I ran some test runs last night and this morning ... haven’t had the issue pulling 11 lbs smoothly ... I’m keeping my eye on it .. and I’ll go through it more this weekend
