About this product

Part #: 40465B

Bully Dog's GTX Watchdog, optimized for 2013-2016 Dodge(R) Cummins(R) vehicles, is a revolutionary leap forward in performance monitoring�loaded with features and our most advanced hardware to date. GTX Watchdog starts up incredibly fast (even when remote starting the vehicle), and is super responsive, sporting a 5-inch capacitive touch screen that rivals today's smart phones. Optimized for Cummins, GTX Watchdog gives drivers the ability to monitor the industry's most extensive SAE and Cummins-specific PIDs, or engine parameters, on an easy-to-use device. High-resolution customizable gauges and WiFi connectivity add to the truly unparalleled user experience. Drivers can log vehicle performance data as they drive at up to 35 frames per second�and play it back later using Bully Dog's free LiveLink software. GTX Watchdog also gives users greater insight into their truck by reading out and clearing Diagnostic Trouble Codes (DTCs). Bully Dog's unique grab n' go magnetic mounting system allows the device to be kept front-and-center while driving, and then quickly stowed away when not in use. Finally, for those who want to take their truck to the next level, GTX Watchdog can unlock 2013-2016 Cummins vehicles (including chassis cab) for tuning using the included Bully Dog Cummins Unlock Cable.

What made you choose this particular product?
I first began researching this product because the stock setting for my speed limiter was 20 mph lower than the car's drag limited top speed, which bothered me out on empty, desert highways. When I looked into different tuners, this one claimed a decent increase in power and torque while not affecting fuel economy or actually increasing it. The reviews affirmed these claims and reassured me that the tune would not fry my ECU. I also like how this product can advance my vehicle's timing to its most efficient level (2 degrees) at the cost of emissions increasing.
Is this your first time buying from this brand? Did you consider other brands?
Yes. Other brands were either too risky for my car's ECU or too expensive for the benefits they delivered.
Was it easy to install? Any installation tips that will help others?
This product plugs directly into the OBD2 port of my vehicle. For power, there is a USB cord so you can bring a laptop in the car when you want to tune. Permanent powering is harder because you would have to drill through the dashboard to the fuse box and splice in the wires. I chose not to do this because I only need it for periodic tuning so I just take the product out when I'm done.
Once you've had a chance to use the product, did it meet your expectations?
Good bang for the buck. Increased top speed from 110-130 mph, increased HP from 175-200 (not dyno tested), and increased torque to the extent that I do notice a difference. WOT acceleration is also enabled under 40 mph, which can be fun with the paddle shifter.
