Buying Considerations of Best Diesel Tuner For 6.7 Cummins
Now that you know the 10 best tuner for Cummins 6.7, no longer do you need to do so much homework on which brands are the most popular for your Cummins truck engine.
However, it’s always better if you know all about the product that you want to buy so that you’ll be able to get the most ideal choice for your needs.
With that said, we’ve also arranged a buying guide to help you understand the factors and precautions when buying the right tuner for your truck.
Before you buy your tuner, always take note of these buying factors:
01. Ease of Set Up and Use
The first thing that you would have to consider when you’re looking for a good tuner would be the overall ease of use.
Most tuners would have a lot of cords and wires that you’ll have to arrange. If you don’t like doing all of that, then you need to find a tuner that doesn’t require much setup.
Bully Dog products are some of the easiest tuners to use. They only require about less than an hour to set up, and they’re really easy to read.
With that, this is probably one of the brands you’ll want to consider buying if ever you’re a beginner.
02. Time Frame
When it comes to ECM tuning systems, one of the most important factors that people take into consideration would be the time frame for the ECM download.
Generally, the less time it takes for the download, the better the system.
Some of the best tuners with regard to the time frame would be the RaceMe products.
These ones generally take around 5 minutes to download which is really impressive for tuners.
The Smarty 98.5 Tuner also has a very fast download time of around 6 minutes depending on the data that you’re handling.
03. Power Levels
Power Levels refer to the horsepower that the tuner can give the engine. So far, the best tuners would usually give off a power level of 10.
Average power levels would range from 7 to 9 depending on the brand that you buy.
However, the key here is to look for the brands that have the highest power levels so that you can get the best bang for the buck when it comes to engine horsepower.
When we talk about storage, you will basically be looking for the number of tunes the tuner can be able to store at a given time.
A good figure would be 9 to 10 custom files that can be stored in the tuner.
All the brands that we’ve mentioned in the list are pretty good when it comes to storage as they’re on the average to the high side.
05. Monitor Size
The reason why we included monitor size would be because small monitors with small fonts might give you trouble with reading.
If you have trouble seeing numbers in small sizes, then you may want to consider buying the tuner that has a big-sized monitor or just simply one with big fonts so that you won’t have any difficulty reading the tuner.
Depending on the Cummins truck model that you have, you will need to buy a tuner that is compatible with your truck.
What we usually recommend is that you buy a tuner that has high compatibility with a lot of manufacturers.
That way you won’t have any problem when you start your truck engine tune-up.
When we talk about versatility, we are talking about the ability of the driver to adjust the performance capacity.
This way, it will be easier for you to make changes or do some experiments– especially if you have a rather unique driving style.
So far, the MADs Smarty Touch Programmer has the best features when it comes to versatility and will really make you appreciate a good tuner.
08. Design and Style
Sure, this may not be such a crucial buying consideration, but it is nice to buy a tuner that looks pretty cool– especially if you’re a tech-savvy sort of person.
You’ll want one that has a rather futuristic design. Of course, this factor will really all depend on your own preference.
If you’re not too particular about the look, then you can buy whichever one suits your needs.
We always consider price when it comes to our purchases because the price can be an indicator of quality.
When the product is a little bit too cheap, then you might have to question its performance capability.
At the same time, you wouldn’t want to buy a product that is way too expensive since you won’t have enough budget to buy it anyway.
The best way to go about it would be to look at the average price range of the best products.
What we did is that we collected the best products based on our own tests and reviews from other buyers.
From there, we got the average pricing for all of them and determined which ones were priced reasonably.
Our narrowed-down list has very reasonably priced products that won’t put too much of a hole in your wallet.
Benefits of Tuning Your Vehicle
Of course, the most obvious benefit of tuning your vehicle would be enhancing performance and maintaining efficiency.
Aside from that though, there are other benefits that you’ll get from a good tuning:
Using a diesel tuner is a much better alternative to the old-school power tuning box not only because of better performance but also because of cost.
The best thing about diesel tuners is that they adapt to the existing parameters of your engine and will allow you to change them anytime you want. With that, you don’t need to keep on installing new power tuning boxes.
Easy to Use
With tuners like these, you don’t even need to be a car-savvy person to do tuning because they’re so easy to use.
While there are some tuner brands that are more complex and comprehensive than others, most of the tuners (especially the ones that we’ve mentioned in our list) have very easy interfaces.
With that, you don’t need to learn so much about tuning. Just learn how to use a tuner and you’re good to go.
One of the reasons that most people use tuners even if they’re not really into heavy modifications is because they want to save up on fuel.
As mentioned in the list above, the products do have parameters for fuel economy.
With those settings, it is actually possible for you to set your engine so that it won’t consume so much gas.
FAQs About Tuner For 6.7 Cummins
Q: What is the ultimate best tuner for Cummins 6.7?
A: For us, there is really no one best tuner for Cummins 6.7. We believe that all products have their own respective pros and cons.
That said, we do believe that there is a range of best tuners that you can choose from based on your own needs and preferences.
The 10 tuners that we have mentioned above are the best picks based on their own characteristics.
To find the best one for you, pick out the one with your ideal features by comparing them with the criteria presented in the buying guide.
Q: Are these ten tuners compatible with all Cummins engines?
A: That will really depend on the model you are talking about. For older engines, maybe some of these tuners may not be able to work. However, these given 10 are proven to work for Cummins 6.7 engines.
You have to take note of the level of compatibility as well. Depending on your Cummins 6.7, you may consult with the technician to know if your desired tuner works on your specific engine.
Q: Does Cummins, Inc. only manufacture engines?
A: While their main job is manufacturing high-quality engines, they also design and innovate various kinds of powerful engines.
Aside from the diesel-fueled engines, they also design and manufacture alternative power engines for those who are more eco-friendly.
Q: What exactly do I need a tuner for anyway?
A: To put it simply, a tuner, also known as a programmer, is a small device that is used to maximize the engine’s overall potential functions including power and features through a plug-and-play mechanism.
Some of the features that a tuner would maximize include horsepower and torque.
Other than those two, tuners also enhance the overall smoothness and efficiency of the engine so that it won’t die out or wear out too easily.
Q: What is the maximum amount of horsepower that I should add to my engine?
A: This will really depend on your engine, but we do not recommend that you go beyond a horsepower of the 120 level unless you have extra head studs just for safety.
If you have a high-maintenance engine that is built for speed and would want to increase horsepower, get the right head studs for your engine so that you won’t overheat it when the engine powers up too much.
Q: Are extra head studs enough if I frequently drive with high horsepower and want to tune the engine even higher?
A: For those who want to have higher tunes, then we suggest getting a valve body swap.
However, we do not recommend that you run higher tunes if your truck won’t be able to take it.
For example, the tires with the larger tires won’t be able to take higher horsepower since the larger tires will have more resistance on the ground.
With that, we actually recommend that you keep the horsepower to a level between 30 and 50, so your head gasket won’t blow up.
Q: Which of the products would be recommended if I am the thrill-seeking speed demon type?
A: While all of the choices are pretty good for speed demons, the best product would most likely be the MADS Smarty S-67 Programmer since this one has a range of 10 levels, allowing you to reach high levels of horsepower for your pleasure.
Q: Can the shelf life of the engine be extended through tuning with these products?
A: Typically, the tuning would be able to extend the life of the engine and other parts like the gearbox and the clutch by making the movement of the engine interior smoother as well as controlling the power.
Of course, this would depend on how you tune the engine too. If you stress the engine too much by adding too much power, you might reduce the life of your engine.
In the end, this would depend on what you want to do with your engine and how you tune it.
Q: How do tuners help with fuel economy?
A: Depending on which tuner you buy, it usually increases the miles per gallon.
There are some that can even get you the fuel economy of a smaller vehicle so that you can save up on diesel.
Of course, you have to do due diligence as to whether your engine will be able to take a certain level of fuel economy.
