I received the F5 quickly. I read the directions and plugged it in my truck. It is very simple to use and I tuned the truck quickly. Now driving it is different. It is peppier and my fuel average went from 11mpg to 16mpg. It's a Dodge Dakota with the big v8. I will set it to towing when I pull my trailer and I'm thinking it will have better power on the hills and better mpg too. I would recommend this product to anyone.
Bigger tires, changes gears? You need this!
This tool worked well for my 2015 Jeep Rubicon Unlimited. I recently upgraded the tires to 35" and the tool worked flawlessly to set the speedometer to reflect the new tire size. This is vehicle VIN specific; once it reads your Jeep's VIN its locked to it.
Superchips TrailDash2 Jeep Tuner
This tuner is really is everything it's advertised as. I don't use many of the features yet but with a little tinkering it's easy to navigate the menu options. The performance tunes work really well. Really woke of the 5.7 HEMI in my Jeep. All touch screen and if you want to make it your primary monitoring system it mounts nicely above the dash. Highly recommend this for anyone looking for some extra performance or even wants to get a little better gas mileage.
