Review on 🚀 Bully Dog GT Platinum Diesel Diagnostic and Performance Tuner - 40420 - With 4-Preloaded Tunes by Michael Gupta

I recently switched to diesel and had no idea about the performance potential of diesel engines. I have a 2006 Dodge Ram 2500 with a Cummins 5.9 diesel engine, it's a Rock Stock truck with 85,000 miles on it. Installing the Bully Dog Tuner changed the behavior of a very capable work truck into an 8,000 pound Corvette. I'm amazed at the power and speed the truck has now. I've upped my mileage from 14-16mpg to 17-21mpg, I find it better to keep my foot out of the way. The tuner has four performance options and you can change them on the fly in a Dodge. I've used three of the four: 1. No power (like stock) 2. Towing/towing 3. Power 4. Extreme, I don't want to try number four as they recommend that you upgrade your transmission to handle the extreme setting Use number four. I highly recommend it and would buy it again in a heartbeat.
