Will recommended to everyone i know!" —Thomas B from Lake Villa, IL bought a Superchips Flashpaq Tuner for a 2004 GMC Sierra, 5.3L V8.

"Running this with my K&N FIPK intake I also got on autoanything.com my truck went from 13 to 17 in the city and 17 to 21 on the highway running on the performance setting with premium gas. It also gave my truck a lot more acceleration by changing my shift points. The most power it noticed in 3rd gear." —Brandon C from Gaylord, MI bought a Bully Dog Triple Dog GT Tuner (49-State Legal) for a 2004 GMC Sierra.
"The bully dog tuner worked very well with my 3 inch front to back dual exhaust and cold air intake. The power increase was substantial and the milage on my first 70 mile trip was 18 mpg which is impressive for an 3/4 ton 4 door 6.0 truck. I could not get the shift points to work on performance or tow without hitting the rev limiter so I had to leave the download on stock, that was the only problem I had." —David W from Cody, WY bought a Bully Dog Triple Dog GT Tuner (49-State Legal) for a 2004 GMC Sierra, 2500, 6.0L V8.

First trip w/GT was 75 mile round trip over two lane black-top roads w/ speed limits of 55 & 60. It got 18 mpg. I didn't run performance test, but it seems to have more power. Can't wait to see how much better it pulls my 5th wheel camper." —Harold G from Washington, MO bought a Bully Dog Triple Dog GT Tuner (49-State Legal) for a 2004 GMC Sierra, 2500, 6.0L V8.
