Haven't chipped a vehicle in years since I got old, really not necessary anymore. Buddy runs an F-150 with an Edge evolution tuner from Troyer performance , which remaps the factory chip. Nice stuff , you can download the newest tune or get tweaks from Troyer by hooking up to a USB port. Always stores the factory map in case you need to go to Ford or emissions service center or there is a recall.Plugs into the OBDII port under the dash and stays in.
Monitors lots of data points you don't see now , like trans fluid temp, that would be nice when towing. Comes with 3 different tunes loaded.

More money than the others you spoke about , but very proven stuff from a reliable place.
