Had TC fully turned off, held for 10 seconds for triangle with circle in it. Not just DTC.

If you're tuned, could be a post shift timing drop.

Any idea how to fix?
To clarify, your flooring it from a standstill and it cuts power after shifting 1-2 and picks up again and shifts fine 3-7?

Have you tried it in Sport Mode (shifter left) or w/ the Sport Button on? Does it happen in all 4 modes (D, S, D + S Button, S + S Button)?

Also how fast are you going when it happens? For that matter how fast are you going when you hit 7th?

My tuned 2015 F80 with DCT will do the same thing sometimes.

WOT from a stop, 1st gear 2nd using the paddles in M mode. The car suddenly cuts all power when shifting into 2nd and then the car feels like it has no power right after the shift. But when I get back on the gas from 2nd to 3rd to 4th to 5th no issues.

Strange. But why "back on the gas"? No reason to let off the gas w/ DCT. Just click the paddle with your foot on the floor. It shifts slick as can be. Have you pulled the codes?

That's the thing, my instant reaction after having the power cut is to let go of the gas. The power cut is so violent that it feels like throttle is just being cut by 60%.

Does it happen in Automatic letting the car shift itself? Are you waiting until redline to shift?

Nope doesn't happen when its automatic (D). Of course not, I am shifting at 5500RPM<.
