n54 low rpm 1200-1500 WOT misfire

Hey guys. need help with my problem.
I've missed the time when this started, but I assume it was after installing Helix Overdrive. don't know if this relates to the problem )))


The thing is that at low RPMs, 1000-1500, when I press the pedal to WOT, I've got misfires on cylinders 1, 3, and 5. swapped coils, plugs, and injectors, so it's no hardware problem. I'm doing my own tuning, so it could be the tune problem. But as I remember, this problem never occurred. The car is doing great in other situations, like going 9s 100-200.)))
