2004.5 - 2005
The EZ is the ultimate performance upgrade for the driver that wants on-the-fly adjustability, added towing power, quick and easy installation, improved fuel economy, and doesn't want to spend a lot of money.

The EZ offers a simple, plug in installation that requires no expensive mechanic labor, no drilling, and no computer downloading. Simply plug the Edge EZ into 2 stock connections, snap in the power adjustment switch, and you're ready to go.

The EZ provides real power and on-the-fly adjustability, but does so in a safe manner that does not require the installation of additional upgrades or gauges. You can switch between 3 power levels to add up to 65HP ­ all with the flick of an in-cab switch. The Edge EZ carefully monitors timing, turbo boost pressure, and fueling parameters to maximize power, torque, and driveability. The EZ provides power to help eliminate downshifting while towing and unleashes the hidden power of your Duramax, all the while keeping EGTs at a safe level.

The EZ is also tuned with a special fuel economy level* that improves the atomization of fuel, which in turn allows Edge to add power, while at the same time delivering between a 5-10% improvement in MPG when driving in level 1. Add to that the EZ's price point and you have the ultimate value on the performance market today.
