2004 Chevrolet Tahoe LS 4WD 4dr SUV (4.8L 8cyl 4A)
Purchased used with 50K miles. Typical 15 to 18 on the highway. 12 mpg with 16 ft boat. We installed a Hypertech Econ programmer. Boat went to 15 mpg, highway steady 19 to 20 between 60 and 65 mph. Installed a Flexalite electric fan. In my son's words "the fan is sick!" 23 mpg on the highway! Have not towed the boat. Only vehicle in the family that can carry all of us any distance (all over 6'). Power increase is noticeable! This thing is within 1 mpg of our Toyota Camry! Why didn't GM build it this way?
Leather is wearing poorly. One of the gauges has died.
