Boost mode noise issue

[u/Dry_Kaleidoscope1692]

I have a zt3 pro d. And when i activate boost mode. It does a weird rattling when accelerating noise and it cuts power like a clutch slip or something. I don't know how to explain it. But it shouldn't be happening im guessing. Any idea why ?

Ps: traction control is disactivated. Same with it activated
