The Edge Products 30203 EZ Module for your 2003-2004 Dodge 5.9L Cummins is the ultimate performance upgrade for the driver that wants affordable adjustability, added towing power, quick and easy installation, and improved fuel economy.

The EZ offers a quick 10 minute installation that requires no expensive mechanic labor, no drilling, and no computer downloading. Simply plug the Edge EZ into 2 stock connections and you're ready to go. You can switch between 4 power levels to add up to 70 HP. The EZ safely provides power to help eliminate downshifting while towing. 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 one. Add to that the EZ's price point and you have the ultimate value on the performance market today.

The following power gains are representative of an actual test vehicle. These gains were measured on a SuperFlow Dyno at an altitude of 4400 ft above sea level, and represent power delivered to the rear wheels of the test truck. The only modification made to the test truck was the addition of the Edge EZ module. Power gains may vary based on vehicle and geographical location.

Level 1: 25 Horsepower - 50 Foot Pounds of Torque
Level 2: 45 Horsepower - 100 Foot Pounds of Torque
Level 3: 65 Horsepower - 150 Foot Pounds of Torque

Awesome for the money

I have an 03 4 door long bed cummins. I usually keep this on the second setting, also there are only 3 settings on mine but it's 11 years old now, but with 4.10 gears and it being a 2wd running 285/75/18's,i also have 60 hp injectors and a wicked wheel 2, all that being said going 65 down the road I regularly get over 30mpg and I only get 24 without it. So for decent cheap power and this milage it's definitely worth the money
who knows

they advertised 70hp and 220ftlb but i guess they changed it the one i got was something like 50hp and 150ftlb so not to happy about that and 5 power levels, no i got 3 power levels but i did get another 3 to 5 mpg very happy about that but i need fuel pump upgrade for level 3

The product made a noticable increase in fuel mileage and transmission shifting in level 3. However the install sheet says 5 power levels but only listi hp gains up to level 4 & reads that level 1 is "stock". This leads me to wonder, How many power levels there really are???
