Same. It’s the cheapest and easy to install. Doesn’t give you any other features other than speedo and tire pressure setting. That’s all I wanted so it was a great add.

AlphaOBD is a third the price of AEV ProCal Snap and has tons of features

Does AlfaOBD work on 5th gen Ram's? Their website shows 2018 as the latest year for support.

What model truck do you have and what mods did you make? I am trying to get rid of the speed limiter on my 21 2500 Limited.

2021 RAM 3500 CTD. I Changed tire size, added OEM LED headlights and OEM fog lights, and something else, I'll have to look back at my list when I get home later this week.
