Bully Dog Chevrolet Duramax 6.6L Diesel Dyno Experience

During a phone call from Stephen Clarke of Bully Dog Industries, up in Aberdeen, Idaho, he shared with me some performance dyno numbers pertaining to the Bully Dog Power Pup Downloader and nitrous oxide systems for the Chevrolet Duramax 6.6L Diesel. We made arrangements for him to drive the Bully Dog Chevy Duramax down to SoCal for some serious dyno time. About the Bully Dog Power Pup Downloader
The Power Pup Downloader is a computer power program capable of producing 50, 70, or 95 hp, with the ability for the serious off-road enthusiast to upgrade to 150 additional hp. The Power Pup also gives the driver the ability to remove the speed limiter on the '02 and '03 Duramax, and the ability to adjust the speedometer for different sized tires. The downloader contains OBD-II functions to scan and erase engine codes. The customer can also purchase a 150 additional hp code from Bully Dog to be imported into the existing Power Pup unit. An optional dual-stage nitrous installation kit can also been plumbed into the system for that additional instant neck-snapping torque and power. To handle the Duramax's increase in horsepower, it is recommended to install the Bully Dog Transmission Upgrade kit. This kit consists of additional clutch discs to be installed with certain clutch packs. A valvebody will match transmission fluid pressures and shifts with the torque converter and increased horsepower. We called the team at Brothers Performance in Corona, California, known for its truck, engine, and suspension components, to reserve some dyno time on Brothers Dynojet 248C treadmill.
