Duramax LBZ Performance Module 2006-2007

What is the Dr. Performance Pro Performance Module? Simply put, the Dr. Performance Pro Performance Module is a minicomputer that plugs in under the hood and optimizes fuel pressure to create a finer flume of fuel which results in a more complete fuel burn. This results in better combustion quality, efficiency, and power output. That means more torque when you need it, a much smoother power band, and significantly increased responsiveness. Most daily driving in a diesel is spent in the lower RPM range. This is exactly where our module increases power and gives you much more predictable performance through the bottom end of your gears. Unlike a tuner which downloads over your trucks ECM and overrides your trucks safety parameters, our module plugs in-between your fuel pressure sensor and your ECM. That means your truck never operates outside of its safety parameters and you get to keep your warranty! For a detailed write-up on the difference between tuners and our module, check out a
