how's your tune looking? what kinda timing are you running?
Seems normal to me, those rockers float like a SOB.

The fact that I dont know anyone making good power (330whp+) on a m90 and makes more than 13psi of boost confirms this.

its just been to hott to go beat on it
More heat = less air = less strain....
