I use a Superchips tuner (#1705 I think) in my 2001 4x4 F250crew cab. Before the turner and Banks monster exhaust, I was getting 14.5 in town and now I am getting 17.8-18 consistantly.

Even pulling my car in an enclosed trailer I got 16.5 averaging about 60-65 mph.

The power increase is also incredible. The best $311.00 I have spent (programmer cost).
