90 XJ: 4.0, auto, 3.55 gears, 31" tires - gets 16mpg city highway and 14mpg city. Has K&N OEM filter drop in, and Accel coil and wires, and removed the reducer from air box

03 TJ: 4.0, auto, 4.10 gears, 33" tires - gets 14mpg highway (best ever recorded) and 10-11 city. But it is pushing a lot of extra weight.

I wish I got 20 in my XJ, or more <img src="/forums/images/graemlins/frown.gif" alt="" /> it must be nice..
