Short stacks or not? I know they take away from low end tq #s but by how much and is it worth the 3 or so extra ponies up top? I went up 2 in the rear since i figured i would at least be doin the box mod and that would help with the tq down low. Anyone with this mod plz help me out on this because the bike is hopefully going on the dyno sunday and i need to get these on before i get the bike mapped. Oh ya and il be running a BMC Race filter, 42T rear sprocket, full yoshi exhaust, box mod, and of course the pc3 usb to go along with the shorties if i decide to run them.
