if you want more power, get an aftermarket exhaust and get a throttle body spacer. since its a 3 bolt housing. here is the web site for it. its the only one i can find for the 3 bolt throttle bodys. http://rustysoffroad.com/mm5/merchant.m ... de=PER_AIR
i did that to mine and i feel more power from it. hope this helps. mike.
