No I can't say I've really had time to try the A-B-A testing. I have a few more mods then that at this point. Listed below
  1. Grill Blocks - 4 in the summer
  2. Slanted front air dam
  3. Transmission under body cover
  4. Transfer case cover extending back about 3-feet.
  5. Roof rack delete
  6. Several much smaller panels under body - One is only 2" square
  7. Front fender gaps filled
I've also found adding a bottle of Iso-Heet really makes a difference on my Jeep. I read somewhere that the computers on the Jeeps can be tricked with stuff like that.

The reason it says 21% above is because I used the EPA calculator to adjust for the fact that I was only doing about 20% of my driving on the highway each year. So I think it quoted me 14MPG's for the average. Which is about what I was getting average before I joined this group. I need to run the numbers again and see where I'm at these days. I know I've been taking the highway more across town (like a good ecomodder should) and have gone on a few long trips as well. But it's not unusual for me to push 20MPG's all in town on my way home from work at night.
