i ran my 5port with .7 shims and p3 plug & 30% sidewinder this wknd, the motor wouldnt run good under 270s and not good there. i had 1.0mm shims in until i read the shimmin article and i pulled .3mm shims out and the motor was insane and would run at 220 but started flaming on me after a while, could it be the hot plug with the 30% ??
