I have taken several trucks to the Diesel Doctor. They know just how to tune a truck to run really good. Most impressive to me was a 2007 pro star with a cummins engine. I couldn't get better than 5.5 mpg out of it no matter how hard I tried. After the Diesel Doctor set the paraneters and turned the horsepower up to 500 at 1800 pounds of torque not only was the Pro Star transformed into a effin' beast I saw an immediate improvement in fuel mileage to 7.5 mpg
