AFAIK, not confirmed: V8 controller hard limits current at level of 25A, and thats the reason of so called "pendulum effect" when controller cant draw. more power in moment to balance out, which leads to extreme tilt forward or back, then tries to outplay this fast, hits, either, battery voltage drop, or (in case if battery is not an issue, 3P) current limit, starts to oscillate back and forth and cant play it out. Depending on if you have stock battery or modified 3P version you'll either fall down because of voltage drop (read power drop), or have weird second riding wild mustang.
Oh my god you can't be wrong more than that. It's your lack of confidence mistake.
