I'm fairly new to the site and am looking for advice on performance modules / downloaders. I have an 04.5 2500 that is my daily driver and I occasionally tow a 26' race trailer with. My main goal is fuel economy along with a HP increase. I don't want to jeprodize my warranty or throw any codes. I was leaning towards the Edge Milage Max but after talking to them they thought the EZ would be a better choice since it has the three different settings. I have seen some posts on Quadzilla, Diablo Power Puck, and Samrty. I am looking for information good or bad. Thanks in advance for your time.
