I have the bully dog on my 01 Excursion (deisel)....helps with mileage for the towing but makes it a big turd.....the power options are very nice.

We have one on my boss' 02 and don't see any fuel mileage increase over my 01. The 02 is way faster than the 01 but I only pull about 6,000pds. so I just left mine stock.
