Most Popular Evolution for 2021 Ram 3500

It works! Seems rather flimsy. To go from screen to screen is pretty complicated. (Although I'm not the most techno Savey person either!) But in the end it did improve my mileage by a solid 3mpg! So that makes it worth having! I have it on an 07 chevy Duramax used for towing, for that it does a good job!

Just got programmer installed with dash pod, I haven't driven for any amount of time with the programmer running, but the programmer was easy to set up. It has a ton of functions to customize programming, I'm looking forward to using for towing 33 ft fifth wheel. The installation was fairly easy on an 03 GMC Sierra.

It works as promised... our water supply never froze during subfreezing temperatures

Very buggy the unit would have constant crashes just with going through the menus. NEVER TRUSTED IT to actually make a change to my truck.

It works

Works pretty good. I get a mile to the gallon better. When I tow a 13000 lbs fifth wheel camper it really does a great job. More hp and 1.6 mile to gallon better. Now the truck doesn’t shift gears as much.

Not a huge difference, towing my 28' travel trailer, but I do appreciate the firmer shifts and ability to see more engine parameters on screen. Over all, happy with the product. Easy to install and use.
