Bully Dog - Rapid Power (3.0L)


More power. We all want it. But in this economy we all want fuel efficiency, too. How to get both? Here at 4XGUARD, we believe Bully Dog Technologies may have found the solution, and we're proud to feature their engine performance tuning and monitoring kits.


Bully Dog's Rapid Power is a performance tuning module that easily boosts fuel economy, torque, and horsepower.

After about 500 miles of city driving and 5,000 mile of highway driving (about half of which towing a 28-foot, 5,500-pound travel trailer) 4xGuard sums up its experience with Rapid Power:

With it installed I have all but lost the turbo lag, gotten a very noticeable increase in power, and amazingly improved my fuel mileage about 2-3 mpg — less increase on highway (now 21-22 mpg) and more increase city (now 19-20 mpg).  Not bad at all for a rig with such large tires.  It also seems like the shifts are smoother, especially the downshifts.

  • The Rapid Power module improves fuel economy and adds power to the Mercedes 3.0L V6 Diesel engine.
  • Increases the efficiency of the fuel injection system. Results show increases of 35hp and 40 ft.-lbs of torque.
  • Easy installation; the kit comes with OEM style fasteners that snap inline to the fuel-pressure sensor on the passenger side rail.
