How Do I Choose a Tuner For a Jeep Wrangler JK?

Choosing the right performance tuner for your Jeep Wrangler JK can be a little bit overwhelming. There are so many options out there, and each promises to improve your vehicle’s performance in different ways, which can make choosing the right one difficult. Keeping an eye out for the following features will help:

Compatibility

You should first make sure that the tuner you have selected is compatible with the year and model of Jeep you own.

It Meets Your Needs

Will the tuner still function if you change the vehicle’s tires or gear ratio? You want to make sure that this tuner can adapt to changes you plan to make to your Jeep. It should also provide benefits that are useful to you.

Display

If you want a tuner with a clear and easily readable display screen, make sure you are choosing one with an LCD screen, backlit LED screen, or something else that offers a similar level of readability.

Reliability and Accuracy

Your new tuner will be no good to you if it does not offer accurate speedometer readings or have a reliable and safe calibrator.  

Affordability

While tuners can help you get the most out of your engine, they are not miracle machines. You do not want to blow your entire auto budget on a tuner, so choose one that works well but offers good value.

Review of the Best Jeep JK Programmers

To help you make an informed decision, we have reviewed five Jeep Wrangler JK tuners that we think are some of the best out there.

Bully Dog 40417 GT Platinum Tuner for Gas Applications

PROS

  • Dynamic and mountable LCD screen
  • Compatible with the Jeep Wrangler JK
  • Preloaded with fuel-saving settings for daily commuting
  • Code clearing feature allows you to diagnose and clear trouble codes for proper engine operation
  • Comes programmed with multiple preloaded performance modes and 10 slots for custom performance settings

CONS

  • The LCD screen is a little on the small side

What Recent Buyers Report

Recent buyers were impressed by how well they were able to improve their vehicle’s fuel efficiency with this tuner. While many also noticed performance improvements in the form of increased horsepower and torque, mileage increases are where buyers find this tuner shines. 

Why it Stands Out to Us

The reason the Bully Dog Platinum Tuner is our pick for the best overall Jeep Wrangler JK tuner is that it increases performance while optimizing fuel efficiency. Some of the cheaper tuners are dedicated to horsepower and torque improvements while largely ignoring the impact they have on the vehicle’s gas mileage.

We also really liked the clear LCD screen, which allows users to monitor real-time engine updates. The ability to choose from pre-set performance settings or program your own was another reason why we liked this particular tuner so much.

Bottom Line

If you own a Jeep Wrangler JK and you are looking for a tuner to help you get the most out of your vehicle, you should consider the Bully Dog Platinum Tuner. It balances performance and fuel efficiency to make sure your Jeep is running to its full potential.

3571-JL Superchips Flashcal

PROS

  • Affordable price
  • Compatible with the Jeep Wrangler JK
  • Straightforward installation and programming
  • Can be used to program factory and aftermarket lights
  • Works with a variety of common Jeep modifications and aftermarket tire sizes

CONS

  • Small screen can be difficult to read
  • Data transfer feature only compatible with Windows, not Mac OS

What Recent Buyers Report

Recent buyers were impressed by how straightforward the installation process was. Thanks to its fast processor, users also found it delivered almost immediate improvements to throttle response. The intuitive controls and navigation made it easy for most users to work with; however, some had complaints about difficulties reading the small, 2.8-inch screen.

Why it Stands Out to Us

The reason this tuner stood out to us was its ability to accommodate various aftermarket modifications. Where some tuners do not work well with lift kits and oversized tires, this Superchips tuner will still function just as well. 

We also liked that this tuner featured customizable options, as well as pre-set performance, crawl, and tow modes. Superchips designed this tuner with a clear and simplified user interface so anyone can use it without confusion.

Bottom Line

If you are looking for an affordable performance tuner that can help you get the most out of your Jeep Wrangler JK, even if modified, consider this simplified performance tuner from Superchips. If you do not think you will have any issues reading the relatively small screen, it could be the perfect tuner for your Jeep.

Best for the Money:
EDGE - 85350 Evolution CS2

85350 Edge Evolution CS2

PROS

  • Low price
  • Compatible with the Jeep Wrangler JK
  • Ability to alter and increase speed limiters
  • Straightforward tire size and gear ratio recalibration 
  • Features a sleek design and comes with a suction cup mount

CONS

  • Few custom settings
  • A slower processor than other tuners means it can sometimes lag

What Recent Buyers Reports

Most recent buyers chose this particular tuner because it is available at such an affordable price. Given its relatively low cost, most users were impressed with how easy it was to install and use.

Users enjoyed the versatility of being able to choose between an economy mode for improved gas mileage or a performance mode for increased power; however, the lack of custom settings is a drawback.

Why it Stands Out to Us

Given that this is our top pick for a budget-friendly Jeep JK tuner, it is unsurprising that the low price is the first thing that stood out to us. We liked the sleek appearance and straightforward, intuitive interface.

While we would have appreciated the option for custom settings, the preprogrammed modes work well and offer Jeep owners serious mileage and power improvements.

We also liked that this tuner still works even after the vehicle has undergone lift modifications. Given that this low-cost tuner can improve gas mileage in a significant way, it should pay for itself over time.

Bottom Line

If you are looking for a tuner for your Jeep Wrangler JK that offers good bang for your buck, you should seriously consider the EDGE Evolution CS2. It features a sleek design, intuitive controls, and impressive functionality at a low price.

Honorable Mention:
Superchips - SPC-3571

BRAND NEW SUPERCHIPS FLASHCAL F5 IN-CAB TUNER,GASOLINE,COMPATIBLE WITH 2007-2018 JEEP JK WRANGLER

PROS

  • Sleek, hand-held design
  • Full-color dynamic screen
  • Reads and clears diagnostic trouble codes
  • Corrects speedometer for tire upgrades ranging from 26” to 42”
  • Ability to program auxiliary lights and other aftermarket accessories tied to the same fuse

CONS

  • Data transfer feature only compatible with Windows, not Mac OS

What Recent Buyers Report

Recent buyers enjoyed the ability to recalibrate their speedometer after installing oversized tires. Given how many Jeep Wrangler JK owners add oversized tires for off-roading purposes, this function proved to be popular. 

While some found the screen a little bit small and difficult to read, others enjoyed the compact, hand-held design.

Why it Stands Out to Us

As with many recent buyers, we liked how this tuner lets you accurately recalibrate the Jeep JK’s speedometer for tire modifications. We also really liked its ability to control auxiliary lights and adjust them for daytime running. 

The fact it is updateable through the internet makes sure that this tuner will always have the latest features, but we were a little disappointed that it is only compatible with Windows and not with Mac OS.

Bottom Line

We gave this tuner an honorable mention because it delivers what it promises – a convenient way to improve the performance and mileage of your Jeep Wrangler JK. We enjoyed the discreet size of this device and its overall level of performance.

DiabloSport 8245 inTune i3 Platinum Performance Programmer 3rd Generation inTune inTune i3 Platinum Performance Programmer

PROS

  • User can create custom settings
  • Sleek design and dynamic LCD screen
  • Comes preloaded with effective tunes
  • Can improve speed, horsepower, and general performance
  • Compatible with superchargers and other aftermarket modifications

CONS

  • Touch screen somewhat frustrating and unresponsive 
  • Poor customer service compared to some of the other brands

What Recent Buyers Report

Most recent buyers were impressed with how easily they could disable their speed limiter, increase gas mileage, and improve their vehicle’s overall performance using this performance programmer. Where some programmers can take a while to figure out, most users found the DiabloSport 8245 was intuitive. However, some users found the touch screen was not sensitive enough and left them wanting more.

Why it Stands Out to Us

The reason this tuner caught our eye was how easy DiabloSport makes it to switch between preset tunes and custom settings. We also liked how easy it is to update the device with the latest software.

While the touch screen might be a little less responsive than we would have liked, the screen is still easy to read and navigate. The relatively large LCD screen displays all of the information you would need, so you do not have to worry about connecting it to a laptop for readouts.

Given the improvements you can make to your Jeep’s overall performance using this tuner, it is surprising it is available at such a low cost.

Bottom Line

Overall, we found this was an effective programmer for the Jeep Wrangler JK, and it is available at a very reasonable price. The clear and intuitive touch screen helps this tuner stand out from the competition.

What is a Tuner? What is a Performance Chip? Are They The Same?

Tuners reprogram your engine’s computer to give it more aggressive mappings, where a performance chip sits in the ECU to intercept signals and modify them to make more power.

Do Performance Tuners Really Work?

Performance tuners work quite well. Many can adjust automatic transmission shift points and have many mappings for different performance and economy settings.

Are Tuners Universal?

Performance tuners fit a specific list of makes and models. Usually, the manufacturer explicitly lists the makes and models that work with their tuner. Tuners also work with either gas or diesel engines. While they may not necessarily be universal, some will work with a wide variety of vehicles. Just make sure you are checking compatibility before you invest in a new performance tuner.

Pros and Cons of Tuners

Here are some other things to consider when shopping for a tuner:

Pros

  • They can increase horsepower and torque

  • They offer increases to gas mileage

  • They allow you to monitor your engine’s performance

  • They give you the ability to increase speedometer limits and calibrate the vehicle to function smoother with modified tire sizes

  • They allow you to read and clear diagnostic codes without having to visit a shop

Edge 85350 Edge Evolution CS2

Cons

  • You could run into vehicle warranty issues with certain dealerships

  • They often require regular software updates, which can be frustrating and time-consuming

Conclusion

If you are looking for a way to get the most from your Jeep Wrangler JK’s engine, you might want to consider investing in a performance tuner. A tuner will give you the ability to alter and monitor your engine’s performance. The tunes will increase torque, horsepower, and efficiency. They can also control your vehicle’s lights, speedometer, and transmission shifts.

Any of the tuners reviewed above would be a valuable addition to your JK Wrangler build.

People Also Ask

If you still have questions, take a look at some of the most common things people wonder about when buying a tuner.

How Much Horsepower Does a Programmer Add?

Horsepower increases will depend on a variety of factors, but on average, most users notice horsepower increases in the 5-10% range. On the higher end, some users will find overall power increases closer to 15-20%; however, these higher horsepower settings will sacrifice fuel-efficiency.

How Much is a Programmer?

As this list shows, performance programmers/tuners are available at a variety of price points. Usually, you can expect to pay somewhere in the region of $400 to $700 for a high-quality tuner; however, there are more affordable options available below $400 that have fewer features.

Cory

Cory epitomizes the 'function over form' debate. His XJ Cherokee has taken many a beating due to his lust for climbing the tallest ledges he can find and is armored to the max. Welded on sliders, tube fenders, and no bumpers allow him to achieve some pretty crazy approaches. We regularly tease him that there's more rust than paint on his rig, but that’s his style. Cory's favorite new mod is a larger winch he bought off a buddy after his Smitty cooked itself, trying to yank his buddy out of a ravine.
