Our Pick: Superchips 42050 TrailDash 2 Programmer w/Mileage Coach Software TrailDash 2 Programmer – the best tuner for Jeep JK
- Superchips 42050 TrailDash 2 Programmer; w/Mileage Coach Software;
The Superchips TrailDash 2 Programmer works with Jeep Wrangler JK manufactured from 2007 to 2014. It’s a user-friendly tuner with a big 5″ touch-sensitive screen. Plus, you get three devices in one: it’s not just a tuner, it’s also a monitor and a performance tester.
6 Pre-Loaded Tunes With More Options After to Fine-Tune
The Superchips TrailDash 2 Programmer comes with different power levels that are programmed based on numerous driving scenarios. You’ll get a tune for 87, 89, 91 and 93 octane fuel, Mileage XS for fuel efficiency, and an exclusive tune for the JK called “Crawl”, which is designed for precision maneuvers in low-speed off-road conditions. After you’ve picked a power level, you can adjust specific vehicle functions like the Rev Limiter, Speed Limiter, Fan Settings, and Pedal Response. If you mess up and enter the wrong data, there’s always an option to reset the values.
Test Performance Gains Easily and Keep an Eye on the Engine
What’s nice about this Superchips tuner is that you can thoroughly check how well the power level and any customization works on your JK through the Performance Tester menu. You can check its gains through the 0-60, quarter mile, and horsepower tests. After running these tests, you’ll be able to adjust your adjustments again or pick a different power level.
The TrailDash 2 also allows you to access everything that your car’s computer is monitoring. This will help you see if you need to change your oil, if it’s overheating, and so on. When you have a clearer view of what’s happening under the hood, you can prevent serious damage that would probably need lots of money to fix.
Why should you get it?
If you want to make a lot of adjustments to your Jeep Wrangler JK, the Superchips TrailDash 2 will make it easy. It’s a full-featured device that does a great job improving the horsepower and torque. On top of that, you can also monitor the parameters under the hood, and do performance tests to help you figure out if you got the gains you wanted.
- Exclusive Crawl Tune
- Packed with six pre-loaded tunes
- Allows you to monitor your parameters
Great Value: Superchips 3874 Flashpaq F5 Programmer
- For 1998-2006 4.0L Jeep Wrangler TJ Models
Even though you can’t monitor parameters like you can with the TrailDash 2, the Superchips Flashpaq F5 Programmer is great for tuning and general calibration. This device can let you maximize the loaded tune by letting you manually adjust parameters; it’s especially helpful if you drive it on challenging terrains. It also lets you clear your diagnostic codes in your garage to get rid of that engine check light without going to the dealership for a scan.
This specific model is compatible with 2007-2014 Jeep JK model years.
Pre-loaded with Powerful Tunes
The Superchips Flashpaq F5 Programmer has pre-loaded tunes: Towing, Crawling, and High Performance. These just the computer based on how your Jeep JK to perform. Don’t worry about messing up though, because before the F5 installs the new tune, it’ll automatically a back-up of the stock tune so you can restart if something goes wrong. (It’s also good to go back to the stock tune if you need to bring your Jeep back to the dealership.)
Like the Superchips TrailDash2, the Flashpaq F5 offers the Crawling tune, an exclusive tune for the Jeep Wrangler JK. In case you missed the description in the TrailDash2 review, the Crawling tune lets you perform precision driving when you’re off-road in low-speed conditions.

After tuning, there are special parameters that you can change, like adjusting the TPMS (tire-pressure monitoring system) if you installed different size tires. Adjusting your parameters after changing your Jeep’s parts will also make your speedometer accurate again.

Having the right tune based on your vehicle’s specs will guarantee you optimum performance. It’s easy to jump in with a pre-loaded tune and then make adjustments according to how your Jeep has been improved since you bought it.

Get your Jeep working like a monster on rocky or muddy terrains with the help of the DiabloSports inTune I3. It is a plug-and-play tuner that allows you to upload a tune, calibrate parameters, and clear diagnostic codes easily. It’s designed to increase fuel efficiency and overall performance, making it a must-have device for those adventurous owners who want to drive to the top of the mountain.

The programmer is very easy to navigate with its full-color touchscreen display. The menu is really easy to navigate so you can quickly find what you’re looking for. You can also connect it to the Wi-Fi to update the software directly, instead of connecting it to your computer. You’ll still need your computer though if you bought a custom tune from DiabloSport or a local tuner. It supports Windows, Linus, and OSX .
Use a Pre-Loaded Tune or Adjust All the Parameters Yourself, Plus Clear Trouble Codes
The DiabloSport inTune i3 Tuner comes with pre-loaded tunes. These are based on the fuel that you use, and the specific performance that you want to achieve.

Why should you get it?
It’s a user-friendly device, even if you’re a beginner and just want to see what a pre-loaded tune can do.
