Because of this, we have created this review to help you decide.


What ​is ​a Tuner ​or Chip?

What Is A Tuner Or Chip


It is clear that every tuner on the market today will generate huge power gains in a diesel. With the capability to run on a wide air/fuel ratio, most diesel engines respond well to tuning.

So, if all of the tuners yield big power, how will you know which one is the right product for you? Tuners are anything that improves the engine performance. There are things that you need to consider in choosing a tuner.

Things to Consider in Choosing the Best Duramax Tuner

1. User Interface

There is one important factor that you need to consider and one that is based on your specific needs. All the tuners tested have some kind of display that is ​intended to be mounted on the windshield or dash. The sizes may vary from 2.4-inch display up to 5-inch touch screen.

Generally, the product is mounted on the A-pillar together with some gauges using an aftermarket holder. People are now ​looking to get away from conventional gauges and depend more on the displays for information. This is where size becomes a factor.

All devices with touchscreens have the same issue. People are accustomed to the sensitive screens used by our phone​s. Most of these touch screens use a pressure sensor and need a much greater force than people are used to. If you are not using the screen that much, then it is not an issue. But if you regularly try to move through the screens, then it becomes annoying.

2. Display Options

This is one of the biggest changes in recent years​. Tuners were originally large and bulky. It took a long time to program the vehicle. A good Duramax tuner can be configured to display different parameters on a black and white display.

Some of the tuning companies have modified the display options. The display has a limited color pallet, but you can see it clearly in the daylight.
