"I love this. It's so nice being able to watch what my truck is doing at all times. Noticed a little power gain on top end. Gas mileage def improved. Went from 14.5 to 17-18.... Totally happy with it and glad I got it. Auto anything was also great....way cheaper than anyone else and everything was as advertised" —Waynette R from Moore Haven, FL bought a Bully Dog Triple Dog GT Tuner (49-State Legal) for a 2000 GMC Sierra.
