2004 - 2008 GMC Sierra 3500 Automatic Transmission Control Module 8 Cyl 6.6L PPE Diesel

Pacific Performance Engineering (PPE) is leading the way in electronic high performance diesel technologies for Chevy, Ford and Dodge. Founded in 1985 as a Diesel performance facility we quickly found new ways to improve upon the factory platforms. As technology increased so did our need to explore other options of developing power. In 2001 we 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. We quickly learned that efficiency of the engine could be increased by raising the fuel rail pressure and increasing the pulse width and rate. Today there are many corporations experimenting with the benefits of increased fuel pressure. So far the results have been very beneficial and include increased power, mileage, reliability, lower exhaust gas temperatures, and overall efficiency.
