"Timing advance and throttle sensitivity made it a completely different truck, I have the big tow gears so it had good pull already. I kick myself for not getting it sooner... as far as fuel economy, if you pay attention to the coach you will do better but it seems like it takes the fun out of it! Only downfall is no speed adjust for larger tires and shift point adjustment. Definitely a great product and display is not too big so mounting locations are just about limitless." —Kevin A from Savannah, GA bought a Bully Dog Triple Dog GT Tuner (49-State Legal) for a 2011 Subaru Impreza.
