Most Popular Performance Tuners for 2021 Ford Ranger

very well packaged! could not do better by shopping in person and hand carrying my product home!

Product performs as expected. What's important to me is the company I purchase from.. The follow up from the etrailer team is excellent!!!

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

Simple to use with easy menus and update process via your computer. Don't expect a dramatic power boost with gas engine. I have noticed much improved mid range throttle response, especially at higher elevations. My 2500 HD no longer has to downshift 2 gears to maintain or increase speed on 5 to 6% grades in winding turns in the 45 to 55 mph speed range. Wide open throttle passes at higher speeds seem to be a bit quicker. To soon to form any opinion on fuel mileage.

Thank you etrailer for your awesome customer service. etrailer will be my go to site for all my automobile needs.

The service of e-trailer has been great, and once programmed the device seems to be good (I am yet to put many miles on the truck to see if it does as advertised). The problem with the device is the upgrade software. It took me more than 8 hours to finally get the device upgraded. The design of the software leaves a lot to be desired and the device kept timing out during the upgrade process that rendered the device useless and required a complete restart of the upgrade process. If you buy the device and decide to upgrade it as suggested then you need to have high speed internet, turn off all virus and firewall protection, and be patient because the software does not respond quickly and sucks up all of the computer resources so don't do anything else during the upgrade process. This is no fault with etrailer who were better than responsive in getting the order out and delivered.

If I would have known that when I wanted performance and or heavy towing I was going to have to use 91 octane, I might not have purchased the product..... I can't decide if its worth the extra cost of 91 octane gas.....

It's ok but theres alot better tuners out there this didnt even have a 93 octain tune so my suggestion is pick a different tuner
