5 Things You Must Know While Choosing The Best Tuners For Duramax

1. Custom vs Off Shelf Tune

When it comes to tuning a diesel engine, there are a lot of variables that need to be taken into account. Every vehicle is going to have its own set of unique numbers and characteristics. The more custom work a tuner can do the better off you will be because each tune is going to be finely adjusted for your specific truck. If a tune is generic, it likely has a basic strategy behind it that will work well on lots of different vehicles but not as well on yours specifically (Not always the case but generally speaking). Be wary of companies offering “One size fits all” tunes.

2. Hydra Chip vs Others

Hydra chip has been around for many years now and they offer some very good products. They were recently purchased by Edge Products though, which is another reputable company that offers some very good products. However, there are other companies out there like SCT and Power Hungry Performance (PHP) who also offer great tunes with excellent power gains. Hydra chip has a lot of variations in their tuners though, so make sure you know the difference between them all.

3. Transmission Tuning

The latest revision Duramax’s have transmission control modules built into the engine computer itself which makes tuning for these vehicles much more complex than it used to be because both ECM’s need to communicate together. Some tuners only allow transmission tuning through the vehicle diagnostic port by pulling TCM codes or factory scan tool data or require custom programming at an additional cost. Look for a tuner that allows you to program the tranny separate from the engine computer like a transmission programmer or additional handheld device.

4. Mileage Programming

This is another thing to watch for when buying a tuner kit. Many of them have preset tunes for “Tow”, “Eco”, and “Performance”. Depending on what your goals are with tuning, these preset might not probably get you where you want to be. Make sure that if you select one of these modes, it actually changes the shift points in the ECM rather than just spinning up the torque converter lock-up clutch which will reduce mileage slightly but will also create more wear & tear on other components. The best option is to have adjustable shift points so that you can adjust them into your “eco” mode manually if you want.

5. Warranty

This should go without saying, but a warranty is extremely important when buying a tuner kit for your vehicle. None of the companies I have listed here will void your factory warranty by simply adding aftermarket products to your vehicle, so don’t be afraid to look into them because of this common misconception. The only time the warranty might get voided is if you install something physically wrong with your truck or neglect maintenance on it and wind up breaking something unexpectedly that could have been prevented with good preventative maintenance….or maybe if you run out & purchase an off-brand tuner from some random online auction site 😉 Here are links to the custom programming services offered at Midwest Specialties Tuning, Edge Products, and Power Hungry Performance.

Why Do You Need Tuners For Duramax

1. Increase Horsepower & Torque

Everyone knows that adding power and torque is one of the main reasons people tune their vehicles gaining anywhere from 10-40+ horsepower. That’s why customized tuners are such a popular choice. A simple plug and play setup, custom computer chip tuning and aftermarket parts such as cold air intakes and exhausts are just some of the mods that can be added to your vehicle.

2. Custom Driving Modes

Not only will you gain power in your engine, but also in how you use it! With a variety of different driving modes available, you can pick ‘n’ choose which options suit you best depending on what kind of driver you are. Need more mileage? Eco-mode is perfect for this. Looking for better acceleration? Performance mode is exactly what you need.

3. New Features & Additional Parts

Aside from horsepower gains, custom tuners allow access to additional features your truck didn’t have before. These types of tuners give you the ability to update your vehicle with new features such as remote starting, flashing lights, and safety precautions that help keep you safe on the road.

Wrapping Up

The Duramax is one of the most popular trucks on the market. It’s not uncommon for these vehicles to have a few performance modifications made before they are sold, so there are plenty of tuners out there that can help you reach your desired horsepower goals. Here are our top 8 favorite tuner companies for Duramax owners looking to get more power from their ride! Which Tuners For Duramax do you like? Let us know in the comments below!
