does anyone here without extensive mods run an mpx?? what do you think the gains would be on a stock engine with bigger mafs, injectors, exhaust, 10% pulley, that i have already?? looking at the 300hp kit for awhile but dont want to drop the money, could i get the same results or close from a ported 1st gen m90?? or is it really worth the money
