Most Popular Evolution for 2016 Toyota Tundra

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

Easy plug and play 87 octane tune gives better throttle response and shifts reprogrammed the speed limiter a bigger speed on a Chevy Avalanche and it worked perfectly plug and play install took 10 minutes which was mostly running the cable to the OBD port

I love it and the customer service is the best I’ve ever seen

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.
