PPE is famous for it’s mastery of the Duramax engine platform. In 2001 they brought the Duramaximizer to the market. This product was a first and it is still used today to make the fuel system more efficient on the Duramax Diesel LB7. Their team of engineers learned that efficiency of the engine could be increased by raising the fuel rail pressure and increasing the pulse width and rate, leading to increased power, mileage, reliability and lower exhaust gas temperatures.
The PPE team has always focused on supplying more power and torque, and doing so in a way that enhances the OEM operations rather than hinder the natural operations of the vehicle. They achieve this by staying within OEM tolerances and also by utilizing the very best in electronic materials available. After several decades, PPE is still recognized as a leader in diesel performance and is constantly developing new power enhancements for the Duramax platform. They have also innovated products for both the Ford Powerstroke and Dodge Cummins diesel trucks.
The most effective way to get more horsepower and torque comes through altering the factory computer software. Not only do PPE programmers develop a lot of power, they also offer you the features that you need. For instance, the Xcelerator tuner allows diesel owners to make corrections for tire sizes, gear changes, rev limiters, and top speed governors. PPE thoroughly tests all of their products tested on a state-of-the-art Mustang Dynamometer. They also test at the race track, Death Valley, and in the Rocky Mountains.
