Description
The triple dog gauge tuner is a vehicle engine tuner, monitor, gauge and diagnostic device all in a single unit. The GT dramatically improves the utility of several vehicle applications by providing an increase in horsepower and torque and by improving fuel economy through better engine tuning. The GT monitors and displays over fifteen different vehicle parameters (PIDs) and it includes our all new driving coach feature which teaches end users to maximize their vehicles fuel economy potential. The GT performs vehicle diagnostics by reading and erasing diagnostic trouble codes; this level of vehicle transparency isn't offered by any OEM or by any other aftermarket product. Also included is our performance testing feature designed to test a vehicles performance capability on the drag strip; couple this with our free PC analysis software and users can also determine vehicle horsepower. The GT does it all and it works on most late model diesel pickups including Dodge, Ford and GM. Bully Dog tuning devices will not modify or delete vehicle emissions. Bully Dog products that are purchased comply with the Clean Air Act. Tunes that are preloaded in our devices have gone through hours of testing to ensure the safety of the drivers and the environment overall. Custom tuners are required to follow the guidelines of the Clean Air Act as they develop their own tunes for our devices.
