atomic chili motor

[bnR34]

ok, so my brother in law bought a chili motor and a V2 board. somehow he hooked up something wrong and the motor smoked. he thought that it was totally fried so he said i could have it. i attached wires to it and it still runs. so the problem- on my speed checker it reads the same as a stage 2 motor and i hooked it to a car that does not have the "required" 2x2 stack fet's. so is it gone or do i just need the upgrade? and if i do a stack, would a stage 2 be the same?
