About Bully Dog

Bully Dog Tuners

When looking to add power and fuel economy to any diesel truck, typically the first thing that comes to mind, or is recommended, is to install a diesel programmer or chip. Unbeknownst to many, adding horsepower can and WILL deliver additional MPG's, so you can basically have your cake and eat it too! But how? Simply put, unless you consistently drive aggressively, having the extra power will make the job of moving your 8,000+ pound truck easier, hence not having to work as hard.

But now, which one is right for you? Bully Dog Diesel has been in the diesel performance tuning industry since 1998 producing various Bully Dog Tuners and have gained loads of notoriety for their various devices and tunes over the years. For anyone that's been affiliated whatsoever in the industry for some time will remember the days of the Power Pup and Crazy Larry tune files that delivered unparalleled ground pounding torque. But from those days, Bully Dog Performance Chips have come a long ways in terms of tuning and the devices which carry those tunes. With intuitive tuners and monitors such as the GTX and BDX devices to tune your truck that feature WiFi connectivity for easy updates to their GTX Watchdog for gauges and diagnostic troubleshooting, and everything in between, Bully Dog Performance has a solution for every need.

And guess what, Bully Dog isn't merely limited to programmers. Seeing that the industry needed a lifetime serviceable DPF (Diesel Particulate Filter) that outflowed the factory units at a comparable price, Bully Dog went to work and released their line of Performance DPF's that allow you to have the added power you want, without all of the headaches. If Big Rigs are your thing, the Bully Dog Big Rig division is for you. With advanced tuning, turbo upgrades, manifolds, and more for Caterpillar, Detroit, and Cummins ISX, you'll gain the extra power your semi needs, plus the extra fuel economy that will deliver a nice dividend each month. Especially if you're an owner-operator that's looking to reduce expenses, the ROI on these upgrades is impressive, coupled with the fact you'll be passing the rest of the pack up those grades.

The increase of power is noticed, BIG TIME. Very simple installation. Worth every dollar you $pend. You won't be disappointed.

The Bullydog GT really opened up the power in my 2014 Dodge Ram 2500 cummins

NTBSOT
Great product. Simple install. Noticeable power and performance. I like the defueling, comes in handy here in Texas when it's blasted hot out and your running the heck out of the truck.

Brad
I keep the Bully Dog on my truck at all times. Never had a problem with it, and being able to change the mode with the touch of a button is awesome. Easy to install and use. Have recommended to several people.

Aaron
Easy install. Customer service was great. Having had it long but can feel the difference when towing.

Bullydog gt tuner works great on my 08 dodge 2500 6.7l. The power levels are perfect for what I use it for. Towing heavy loads on the tow tune are much better. The truck rarely downshifts going up hills unlike before without the tuner it would run out of power. I recommend the bullydog gt diesel tuner to anyone the a diesel truck!
