Motor wise it's stock and I haven't done a thing to it. Other parts have been replaced because I wheel it and so changed stuff to perform better. When I bought it, it needed a new clutch but that's all that's been wrong mechanically. Pretty good for an unreliable vehicle.

I'm probably getting around 14 in my Jeep and my buddy is getting closer to 17 in his. Not bad for lifted gas hogs

It's cheaper on fuel to tow my TJ with my 3/4 ton diesel than to drive it. There fun to drive as a second fun vehicle but not at all practical as a daily driver.
