Best Tuner for Jeep JK User Buying Guide

Tuner for Jeep JK

Buying special parts as tuner shouldn’t be random. There are a lot of facts and asking on Google and you have to dig it down before purchasing the best one.

However, we sum up some of major facts, you need to have a look:


The first and last priority that is advisable to consider when buying a tuner for your Jeep is its compatibility with your vehicle. At the same time, a tuner might be affordable and comes with all the right features you desire.

Otherwise, if it is not compatible with your vehicle, it will be a total waste of money. Read some reviews from customers who have used the tuner as well as the manufacturer’s guide to ensure the tuner is compatible with your vehicle before buying it.

A brand can come with different models of the tuner to cater differently to every vehicle’s need, so be wise to take note.


The display of the tuner is another thing to take note of when buying one. Some tuners were designed with a widescreen, which displays multiple parameters of your vehicle at the same time.

Other tuners come with a backlit LCD screen, offering very little flexibility of what can be displayed. While the former is more expensive, the latter is quite affordable.

In other words, how much you are willing to pay will determine the type of display you can have on your tuner. Similarly, tuners with a widescreen are most often come with a capacitive touchscreen, giving you the flexibility to easily navigate through the menu of the tuner.


While many people might not say much about the accuracy of a tuner, it is another very important aspect that shouldn’t be overlooked. The accuracy of a tuner is one of the main factors to look out for when buying a tuner.

A tuner that doesn’t offer accurate readings will end up causing more harm to your engine than increasing performance. So, take note of the performance, preferably, read the experiences other users have with the tuner before committing to buy one.

Because when you change the tire of your vehicle and the gear is not fixed accurately, it can lead to a lot of mishaps.


Most tuners come with preloaded tunes that tune your vehicle to achieve a certain level of performance. Similarly, such tuners can also feature the ability to upload custom tunes, which allows you to tailor the different levels of performance from your vehicle.

Every tuner is designed such that it improves the certain performance of vehicles like throttle response, fuel economy, efficiency, horsepower, drivability, and so on.

Fuel type is another factor that needs to be put into consideration when buying a tuner. Some tuners are engineered specifically for gas engines, some are for diesel engines, but others are designed for both gas and diesel engines.

Irrespective of the type of fuel your engine uses, being able to optimize fuel consumption is important. Take note of the type of fuel your vehicle engine uses before buying a tuner.

We don’t recommend buying a gas engine tuner for a diesel engine and vice versa.


Having a budget is also another important aspect to consider when buying the beat Jeep JK tuner. High-end tuners are often pretty expensive, although there are other affordable options you can choose for tuning your vehicle.

The difference between these two tuners is the flexibility they offer you. While on high-end tuners, you get the flexibility to tune more parameters on your vehicle, the more affordable tuners offer let’s functions and tuning.

Ans: With a tuner, it’s possible to increase the horsepower of a gas or diesel engine performance. Most tuners can increase the horsepower of a gas engine up to 99 horsepower.

Also, the 88 lb-ft of torque and can tune a diesel engine up to 120 horsepower and 240 lb-ft of torque, depending on the model. To know the exact amount of horsepower a tuner can add to your engine, the capacity of your vehicle’s engine, as well as the model of tuner matters.

You are most likely to get more horsepower from your tuner if you have a better flowing catalytic converter. You can also look for a less restrictive exhaust, although it is more likely to make things louder and make things heavier.

Q: Are engine tuners worth it?

Ans: Contrary to many believe that vehicle manufacturers have already tuned a vehicle’s engine to get the best out of it, with a few thousand dollars, it’s possible to squeeze out a few more horsepower and torque.

Although, it’s important to note that buying a substandard tuner or not installing the tuner properly for your vehicle might lead to some problems in certain cases.

For example, some vehicles will not save you money on fuel because they will cause you to pump more into the engine to suppose the added horsepower gain.

As such, vehicle manufacturers will not advise you to use a tuner, but a tuner is worth every penny as it increases the drivability of vehicles.

Q: Are tuners bad for your engine?

Ans: A common myth about car tuning is that it shortens engine life. This is not true, except the tuner is not properly installed.

If done properly, a tuner will not leave any consequence on your engine other than improving its performance. A tuner increases the horsepower and torque of an engine by adjusting the air/fuel ratio and ignition timing to optimal settings.

Contrary to the belief a tuner damages a vehicle’s engine and transmission, a performance chip can even protect your engine from damage.

Q: Will my transmission be damaged if I install a tuner?

Ans: In all fairness, tuners don’t particularly damage transmissions, but drivers do. It’s important to note that a tuner will deliver as much power as the driver press the pedal.

With this in mind, it is also important to note that a transmission has limits, and when you add a tuner, you are often pushing that transmission closer to its limits.

So, it’s important to take caution and often reprogram their truck to a lower horsepower tune depending on the condition they will be driving in.

For example, a towing truck shouldn’t be towing on a 120 horsepower tune. Rather drivers should de-tune it to around 60-70 horsepower before departing on the trip.

Q: Will the best tuner for Jeep JK increase MPG?

Ans: Yes, a tuner can increase the MPG of a vehicle. Although the amount of MPG a tuner can increase your vehicle depends largely on where and how you drive.

Also, factors like the number of cylinders and the frequency the cylinder is filled with fuel determine how much fuel can be optimized. The beauty of a tuner is that it allows you to easily switch from towing to fuel economy to racing in no time.

Most tuners increase the MPG of a vehicle by optimizing the torque.

Q: Does a tuner have to stay plugged in?

Ans: After you must have set up the tuner, it doesn’t matter whether or not you leave it plugged in or you remove it. You don’t need to leave a tuner plugged in for it to hold a tune.

Some tuners are even designed to be handheld. In other words, after making the necessary tunings, you can unplug it and keep it aside while you drive.

However, if you want to monitor certain parameters of your vehicle’s engine in real-time, then you should leave the tuner plugged in as you drive.

Q: Can two tuners on one vehicle be combined?

Ans: When you combine two tuners in one vehicle is called stacking, which involves combining a module and a programmer or a module and another module in one vehicle.

You can’t stack two programmers together. Stacking can be quite risky because tuners were designed to operate independently.

As such, attempting to stack tuners may cause communication conflict as one tuner may attempt to overwrite the other or block communication altogether.

Q: Will adding a tuner make my truck smoke?

Ans: Unfortunately, the answer to this question is not a definite yes or no. Generally, adding a tuner to your vehicle would make your vehicle smoke because of the increased horsepower and torque.

However, the degree of smoke depends greatly on the tuner.

Q: How do I download tune files to my vehicle?

Ans: All tune files are downloaded into your vehicle through the data port. The data port is commonly referred to as the OBD-II port or, in some cases, the scan port.

The OBD-II port is also the port used to scan a vehicle if the check engine light is on to tell what is wrong with the vehicle. However, the OBD-II port is located on the driver’s side under the dash, near the steering wheel.
