When it comes to hot-rodding diesel trucks, nobody delivers a bite as ferocious as Bully Dog. Since 1999, these guys have been lighting fires under diesel rigs with their hefty lineup of monitors, modules and programmers. Bully Dog’s track record of safely extracting massive amounts of power and torque is how they maintain such a high-profile in the world of diesel performance.

When you’re ready to make your oiler scream like a banshee, there are a few must-have items. Let’s start with control modules. Modules are a quick, no-frills way to add massive power and torque to your rig. Plug one these babies into your OBD-II port and stand by for some stuck-in-your-seat action. For instance, the Bully Dog Dyno Dominator cranks a staggering 171 extra horsepower from a Duramax engine—more ponies than your grandma’s grocery getter even came with!

Take the power a step further and add a performance monitor to the mix. While they don’t actually add power, monitors let you control your module from your driver’s seat. That means you can shift between power levels on-the-fly and tune for special parameters like tire size. The best feature comes in the form of gauges. Bully Dog’s Outlook Monitor displays every engine parameter you’d ever need; MPH, RPM, boost, EGTs, even tranny temperature. It also serves as a virtual dyno that displays horsepower and torque along with quarter-mile and 0-60 times.

The best of both worlds comes in the form of a power programmer. Basically, programmers are a combination module/monitor in one unit. Plug the likes of a Bully Dog Power Pup into your OBD-II port and hang on my darling, you’re gonna go! Extracting huge power gains is no problem for a programmer and it has the added features that you get with a monitor. Kind of like a one-stop-shop for over-the-top performance.

All of these upgrades are readily available and super easy to install. Speed enthusiasts everywhere are ditching their traditional muscle and switching to diesel—hot rods for the 21st century. Don’t take my word for it; check out what your fellow torque junkies are saying about Bully Dog:

"Amazing! The added power I received on just the first setting (50 HP gain) for towing made my truck act like it was on steroids! When I'm not towing my 6 horse trailer, I now get a 2 mile per gallon increase. If you have a diesel truck, don't hesitate to buy the Power Pup as it's worth every penny you'll pay for it."

"installed the triple dog downloader in my 2006 ram. Cannot describe the power and performance the truck now has. It blows everything off the road if you can control it. Worth the investment over and over"

"The bullyDog chip made all the difference in this truck. In stage 2 the truck really comes to life. It makes the 7.3 so much more throttle sensitive it is amazing. The power band is much wider than stock. I couldn’t believe the torque gain in stage 2 and stage 3 is awesome."
