For the 50-State legal GT Diesel Click here


The 50-state legal GT is essentially the same as the Bully Dog GT Diesel, but has an EO number that allows it to be installed on vehicles in California. Bully Dog's 50-State Legal GT is part of the company's commitment to compliance with legal standards. The 50-State Legal GT will be a major improvement to your vehicle with the same great features found on the GT Diesel 40420.

The Triple Dog Gauge Tuner or GT is four products in one; a vehicle engine tuner, monitor, gauge and diagnostic device all in a single unit. The GT dramatically improves the utility of your vehicle by increasing horsepower, improving fuel economy and providing a comprehensive set of monitoring features and diagnostic functions.
Can the dealer detect using the device? Will it void my warranty?
View Staff Answer 
Answer

Most dealerships have no TRUE way of telling that the truck was programmed. It is highly recommended you return your vehicle to stock prior to going to a dealer for service to avoid any hassles or complications. Void your warranty? Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C)) . For best results, consider working with performance-oriented dealerships with a proven history of working with customers.
