Works good for the price, smaller than I assumed. Setting it up was a little confusing but after that it gets the job done.
Impressive but not without flaws

I'm extremely impressed with the power delivery and gauge layouts of the Bully Dog tuner. I run my truck in stock form 99% of the time but use "tow" mode when towing our 28' travel trailer. It makes a very noticeable difference when climbing hills at highway speeds. Of course I had to try the "performance" and "extreme" modes as well. Performance is a huge boost to power, extreme even more so, but I'm unable to use it since my clutch begins to slip. I don't think my clutch is bad since it tows our trailer just fine without slippage, I think the extra power is just too much for it. Enough of the pros though. A HUGE con is that when I was using the "safety" feature that keeps the tunes off until the truck reaches operating temp, my truck would reach the set temp, the tuner would switch out of safety mode, but inevitably, I'd stop at a stop light immediately afterwards, the temp would drop below the threshhold, the truck would shudder and throw a check engine code. I believe it was something along the lines of "fuel system overpressure." It did this a few times before I disabled the safety feature. It's only done it once since then, and it was right after startup. The truck fired up, and as soon as the tuner finished booting up, the truck shuddered and threw the same code. I don't know if it's doing damage to my fuel system when this happens, but it's enough to worry me.

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?

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.
