The Big Rig Power Pup® downloader for CAT was designed with one goal in mind - to add bottom line profits through lower fuel consumption cost in big rig trucks utilizing the Caterpillar engine. The Big Rig Power Pup is simple to install and comes with two tunes: an Economy Tune, and Economy with Power Tune. This downloader has been designed to safely improve fuel economy.

Improved Fuel Economy
The main benefit provided by the Power Pup is improved fuel economy. This product carries the highest improvements in fuel economy available in the aftermarket for any Class 8 truck.

More Power
Depending on the original horsepower/torque rating of the engine this software adds between 40-75 rear wheel horsepower which equates to a 15% gain in horsepower across all Caterpillar® engines.

Internet Updatable
The Power Pup can easily be updated online to account for new Power Pup features, new vehicle applications, and technical support issues. Our online updating program, the CAT Update Agent©, makes this fast, easy and convenient.

No Interference with stock settings
The Power Pup does not affect any factory specialty settings such as: load based speed control, gear down protection, idle control, rev limiters, or speed governors.
