Best Duramax Tuners For Fuel Mileage – 2020 Review

If you, too, own a vehicle that runs on diesel, then you would understand the frustration that comes with paying for diesel time and again. And we all know that diesel is not one of the cheaper fuels. But we have the perfect solution for you!

These tuners for Duramax are all designed to give you the mileage that you have always dreamed of. You only need to pick one for yourself and start saving up.

What Are the Best Uses For a Tuner

There are chances that you’re still wondering why you should invest in one of these units. The answer is simple. They are a lot more useful than we think they are. These tuners are designed for providing us with features that greatly benefit us in the longer run. These include:

Save on Fuel

The greatest advantage that we think tuners provide is the cost that it saves on the fuel. It’s not just a feature stated by manufacturers, but something the users have testified to as well. They are indeed great to run your vehicle with great economic savings on every 3-5 miles per gallon.

Better Throttle Response

A greater mileage is not the only thing that this unit will provide you with. It will also ensure that your vehicle serves with better throttle response. Thus, you experience a great towing performance by your vehicle, which it serves with its ideal horsepower and torque.

Faster Hill Pulling Speed

If you ever had to tow a vehicle uphill, you’d know how much of trouble that is. But with these tuners, the transmission stays higher. And as a result, you find yourself towing your vehicle uphill faster and without any extra troubles. What more can we ask for?

How to Choose a Tuner That Will Help With Fuel Mileage

While some of us may be familiar with these devices and know-how to pick one for ourselves, not everyone may know it that well. For those who can’t figure out what to look for in a tuner that will help them with better mileage, here are a few things to consider.

Horsepower and Torque

A good tuner will add great horsepower as well as torque to your vehicle. Both of these properties are already present in a vehicle, but a good tuner will serve to enhance them in order to provide you with better mileage and save you from all the extra costs that you have been dealing with so far.

Monitoring

A good tuner will allow you to gauge as well as monitor your fuel consumption. This will give you a good idea of when you are going too fast and spending a lot of fuel, or doing the same while towing heavy equipment. Monitoring any activity allows you great control over it. So while you can monitor your fuel consumption, you will also be able to get a better hold over it.

A Little Goes a Long Way

It is true when they say that a little goes a long way. If your consumption is very high, and a tuner offers you gains at 2-3 MPG, then you will experience a great change when it all adds up. So do not let the smaller figures discourage you, because, in actuality, they add up to a lot more than you think.

Why it Stands Out to Us

This item is one of those that comes with a long list of features, but for us, there is one that particularly stands out, and that is the heads up display that it offers for its users. With its wide make, this LCD provides the best display at a very convenient glance for users to evaluate the performance of their vehicle.

Who Will Use This Most

A unit like this with such outstanding features and an exceptional functionality is designed not just for a specific group of people, but everyone. Its features include something for everyone, making it ideal for almost everyone that wants to invest in a new tuner.

What Recent Buyers Report

This unit, with all its features and its convenient functionality, has managed to impress almost all of its users. They find it to be extremely helpful with diagnostic trouble codes as well as great at providing a good fuel mileage. According to users, it is a complete package that no one should miss out on.

Why it Stands Out to Us

Again, this unit is one of our top products and has undoubtedly a great list of features. But the one that we love the most is the speed limiter that it comes with. We all know that faster speed equals poor mileage. But with this device, your vehicle will be sure to stay under the speed limit that you get to decide for yourself.

Who Will Use This Most

As discussed earlier, this unit provides a great monitoring system for racing vehicles. These vehicles need a quick assessment, along with diagnostic trouble codes, and that is exactly what this unit provides. Therefore, it is ideal for all racing vehicles that go out there on the tracks.

Bottom Line

Feel like the top product didn’t suit your needs? Well, here is the perfect alternative for you. This unit, too, is everything you’ll need for better fuel mileage on your vehicle. From controlling the speed on your car to providing prompt diagnostic trouble codes, it will do everything for you.

Best for the Money: Edge Products 85100

Cons

  • Performance may deteriorate with time
  • May require a reboot every now and then for the proper functioning of the device

What Recent Buyers Report

Looking for a unit that has completely surprised users with its outstanding functionality? Then this is the one. Buyers report that they did not expect such a great functionality and efficiency from a tuner that came at such a low price. But it proved them wrong, providing them with better functioning than most standard products.

Why it Stands Out to Us

Wondering what we find in this unit that is worthy of being on this list? It is its pre-loaded custom backgrounds and its ability to allow users to import their own background as well. It is a simple feature, but one that not many tuners come with, which is why we think that this unit stands apart from the rest.

Who Will Use This Most

Not a lot of users are familiar with tuners, or how to use them to optimize the performance of their vehicles. This unit is for all those that want to start using a tuner, but do not know where to start. It will give them a great starting unit, with great functional features, but without costing them as much as other high-end units.

Bottom Line

All in all, save yourself some money and get this unit. Saving on the fuel is not all that you save. You save on the cost too! A lower price tag with no compromise on the features; isn’t that what we all need? What are you waiting for then? Waste no more time and invest in this right away.

  • Customer service provided is not very helpful in case of troubles

What Recent Buyers Report

Users say they were tired of their vehicle’s poor performance and poor mileage, but that was only until they started using this tuner. With this device, they claim to have felt a considerable improvement in the vehicle’s performance. They say it is now a vehicle that gives not only optimal performance but also great mileage.

Why it Stands Out to Us

We think this unit is one of the absolute best that is out there in the market, and its real-time evaluation and monitoring feature completely back up this thought of ours. Most devices only evaluate the system and report trouble codes. But this device allows real-time monitoring for your system so you can make sure everything is in good shape.

Who Will Use This Most

This unit is one that skips over all the complex steps of setup and installation and can be set up in no time. This makes it perfect for all those who have little technical knowledge about these devices or cars in general. Therefore, we think it is ideal for all those using a tuner for the first time.

Bottom Line

No more troubles with installation, or hassles with functionality. This unit works as smoothly as it is advertised, and will be sure to present you with no troubles. Instead, it will only tell you about the trouble codes that your vehicle may face and help you get rid of them.

5. Innovative Performance Chip/Power Programmer

Pros

  • Allows a safe gain of up 50 horsepower and 5 MPG of fuel mileage for your vehicle

What Recent Buyers Report

If you are someone that looks into user reviews before investing in an object, then you may find this unit to be your favorite since the users have only found good things to say about it. While they were not greatly impressed by the mileage gains, they were surely impressed by all the other features that it has to offer.

Why it Stands Out to Us

We love absolutely everything about this unit, but what really makes it stand out from the rest is the money-back guarantee and the lifetime warranty that it comes with. For the manufacturer to present with such offers, the unit must really be equipped with the right features and functionality to impress users.

Who Will Use This Most

As we said before, the fuel mileage gain may not be the best feature this unit has to offer, but it still allows a great addition to horsepower and torque of the vehicle. So if you are looking for a tuner that allows better performance with those aspects, then this device is right up your alley.

Bottom Line

This is a unit that is designed to impress. From greater power and torque to better diagnostic codes, it provides all that you need. Nothing about it will let you be disappointed or even regret your choice. If you don’t believe it, then you need to try for yourself and find out.

What Do I Need To Know Before Buying

After the detailed reviews and the buying instructions, picking a tuner for good fuel mileage might seem like a simple task, but there are a few things that you still need to know. These aspects of these devices are all very important to consider in order to ensure that you are satisfied with your final pick.

Use Matters Too

It is true that a good tuner added to your vehicle can serve to give you a better fuel mileage, but it is not all up to the tuner. How you use the vehicle also plays a very important role in the mileage. If you keep running your truck at high speeds and expect the tuner to make up for it, then it just won’t work for you.

Durability

No tuner will provide you with gain with huge figures. The gains are generally smaller figures, which add up to be greater figures after a greater consumption. So, a unit will only prove its worth when it has been used for a longer time. For this, you need to ensure that the product you choose lasts for that long.

Budget

Like most of the other products in the market, these units, too, come at varying price ranges. Some devices provide greater features at a greater price, and others offer fewer features and more affordable price. Before you start looking into these units, it is important that you keep your budget in mind, so you do not end up spending more on features that you do not need.

Conclusion

You can finally say goodbye to spending fortune on extra fuel just because you can’t get good mileage. With these tuners, you will be sure to get greater gains than you always have. Just look for the right features and pick the right one for yourself, and you are good to go. But along with the tuner, do not forget that how you use your vehicle also affects the mileage.
