Bully Dog GTX™ Performance Tuner & Monitor | 40460B

Bully Dog's GTX Watchdog is a revolutionary leap forward in performance monitoring and has been optimized for your 2008-2016 Ford Powerstroke 6.4L or 6.7L truck. The GTX Watchdog offers the most advanced monitoring screen ever and allows you to monitor more parameters than any other device.

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–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.

Diagnostics & Datalogging

GTX Watchdog also doubles as a diagnostic tool with the ability to read and clear diagnostic trouble codes (check engine light). With integrated WiFi capability, GTX Watchdog is always up to date.

Most Advanced Screen Ever
Bully Dog’s 5” capacitive touchscreen is the first of its kind. Graphics and gauges are displayed in brilliant HD color, rivaling today’s smart phones. GTX Watchdog starts up incredibly fast (even when remote starting the vehicle), and provides an ultra-responsive user experience. A fully customizable user interface means your perfect gauge layout is available at the touch of the screen. GTX Watchdog comes standard with a convenient grab n' go magnetic mounting system, enabling drivers to keep their device front and center–and then stowed away in seconds.

Adjustable Parameters

Axle Ratio
Correct the vehicle speedometer (and fuel efficiency calculations) if you have changed the gear ratio on your vehicle. If no gear ration modifications have been made to the vehicle, then choose the stock setting when the tuner prompts you to choose a gear ratio. This will ensure that no modifications are made to the stock program.

Intake Airbox
Allows an aftermarket intake to be run on the vehicle without a Check Engine Light. For Intake Kits that require tuning, this will provide a selection of available intake kits.

Speed Limiter
Change the top speed that the vehicle will reach before the engine automatically limits the power needed to go faster.

Tire Size
Correct the speedometer if you have changed your tire size from stock.

TPMS
Change or disable the Tire Pressure Monitoring System.
