Most Popular Performance Tuners for Ford Excursion

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

I had to update the tuner two times in order to get the tunes for my truck once I got the tune installed it don’t change my shift points in the transmission my first chip I got back in 2000 changed my shift points as well up the horse power .you would think we’d have better technology in 2021. I had called the tech line about four times and all the techs I talked to were nice and helpful.

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.....

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

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!
