How to Get More Power From Your Diesel
Tuning diesel is a great way to get more power from your vehicle. There are many different ways to tune your diesel truck, from a simple diesel programmer to bigger upgrades like heavy duty clutches, free flowing intercoolers and nitrous oxide injection systems. The key to getting the most out of your diesel truck is understanding how to use all of these modifications together to create a well balanced, safe and reliable performance rig that will not only increase power but also improve fuel economy and driveability.
A diesel programmer (or programmer) is a device that plugs in between your ECM and one or more of the engine sensors and manipulates the signal to make the engine run faster or more efficiently. It is a simple but powerful modification that allows an experienced diesel mechanic to make changes to the engine calibration without having to read out the ECM or remove it from the vehicle.

There are a lot of different programmers on the market from companies like SCT, Smarty and MM3 that are all designed for specific makes and models including Ford 6.7L Powerstroke, Chevy/Dodge 6.6L Duramax, Volkswagen 2-liter TDI and more. Most programmers are handheld devices that come preprogrammed with one or more tunes and can be used to easily download a stock tune back into the ECM.
For the ultimate diesel tuning experience a custom remap of the ECU along with some basic bolt on parts such as an exhaust, an uprated intercooler and bigger injectors can transform your diesel into a bonkers torque monster that is capable of pulling huge loads. Unlike gasoline engines diesels have much more low-end and mid-range power than their petrol counterparts making them ideal candidates for extreme tuning.
