Pacific Performance Engineering (PPE) is a leader in high performance electronic technologies for Chevy, Ford and Dodge. Founded in 1985 as a diesel performance facility, we're quick to find new ways to improve on factory platforms. As technology has increased so has our need to explore other power development options. In 2001 we brought the Duramaximizer to the market. This product was a first and is still used today to make the fuel system more efficient on the Duramax Diesel LB7. We quickly learned that engine efficiency could be increased by increasing fuel rail pressure and increasing pulse width and speed. Today there are many corporations experimenting with the benefits of increased fuel pressure. The results so far have been very beneficial and include increased power, mileage, reliability, lower exhaust gas temperatures and overall efficiency.
