98-02 Dodge 5.9L Cummins

The NEW XZT+ for the 98-02 Dodge Cummins is in a class of its own. New in 2007, we have revived an old product with new technology to offer more features, more power, and better fuel economy for the VP44 equipped trucks.


This one of kind power module will provide an additional 65 HP and 200 Ft. Lbs. of torque to your truck. Installation is simple and takes less than 10 minutes to install with only 2 simple connections made on your engine. You do not “tap” the pump wire and it is 100% invisible to the dealer once removed. Adjustments on the fly are made simple with a 3 position toggle switch. There is an “off” setting, fuel mileage setting, and a horsepower setting available at your fingertips.


To start with, we completely re-designed the XZT+ from the ground up. The core of this awesome module is an extremely powerful 32 bit processor. Quadzilla is the only manufacturer using 32 bit processing for power modules. What this means to you is that we can look at more parameters and provide better fueling and timing control than anyone else. Our fueling and timing maps are more complex than anyone else and it provides the smoothest, most instantaneous power you have ever felt!


Adding to that, the XZT + is also USB updatable with multiple tuning files available for download off of the Quadzilla website. We know that not every person is looking for the same thing in a power module and we decided to offer plenty of options to suit everyone's needs. Whether it is smoke you are looking for, fuel economy, instant power, or no smoke there will be a tuning file available for you. It takes less than a minute to update your module with a USB cable (sold separately). You can change files back and forth as many times as you would like. This is also an industry first for power modules.


Not only does this module have all of these features, but we also guarantee that your truck will be more fun to drive than ever before. This module will compliment a host of other products on the market and improve them greatly, including our XZT and Xzillaraider modules. The XZT+ has the best throttle response of any module in its class, yet it is very docile and has none of the ugly characteristics that many of the other products on the market have.

To make the XZT+ even more appealing, Quadzilla has priced this module to be the best value possible for your truck.  Many of the other products on the market are hundreds of dollars more and do not even provide half of the features that the XZT+ does. 

Xzillaraider XZT series is the BEST answer if you are looking for an economy module. The XZT modules combine great power for towing and they increase fuel mileage. The XZT modules are the only modules that combine performance and dual economy for an economical price. The XZT modules are extremely smooth while giving incredible power throughout the rpm range.

  • Increase fuel economy 1-4 mpg
  • Lowest price in industry
  • Up to 65hp and 200ft lbs of torque gain
  • Simple installation
  • Smooth power delivery
  • Designed for towing
  • Lowest exhaust temperatures

    For me this module was a waste of my money. If you look at the reviews that give it high marks they all seem to have a lot of additional mods along with the module. I don't. Maybe it works well when stacking performance mods, but I think it is a poor choice as a stand-alone. This was my first upgrade and I was very dissapointed. 1) I get a 3 position switch with NO indicator to show which setting it is on. 2) I really have to work at it to tell by way of performance any changes made by the three settings. 3) No noticeable/significant power increase. I did see slightly higher mpg in economy mode. Bottom line is I will be looking for a replacement.
    F Yeah!

    Just installed my XZT+ and man is way better than the Hypertech stage 3 program that I was running. Way more snap off the line(running 47RE stock auto trans)! Love the change on the fly versatility versus a programmer.
    Nice Idle feature

    Truck stumbles over itself on level 3 almost undrivable on the highway.Usually keep it on level 2, would have sent it back but the high idle feature is nice when its -5 outside

    Just put this on my 2000/3500...was looking for a little more snort on the bottom end than the old school Superchips Max-Tuner, and it certainly did the trick! I updated it with the COMP tune, just for kicks, and if you want a good cloud when ya mash it, this is the one; although I didn't detect any more pull through the mid-range on up than the tune it came with. Could be another story with a load behind it though. No fault codes, no hesitation, no surging whatsoever...just smooth, and fairly instantaneous power. Would be nice if the switch had an indexed mounting plate, so you could tell which position is which, but figuring it out wasn't exactly rocket science either. Great product and simple install...you'll LOVE IT!
    Not bad at all.

    I bought my 2000 5.9 auto a few months ago with 130k on the clock. It was bone stock and the first thing I did was add this box. It took me about 10 mins to get it installed and crank it up. From the very start I updated it with the most aggressive tune you can get from their site. The power increase was very noticeable and made the truck much more fun to drive around town. A week ago I added a 5" exhaust, 40hp injectors and an intake. Now it makes even more of a difference when switching it off and on for comparison. For the cash, this is a great little performer. Just wish there was another tune to fuel a little bit harder.
