When it comes to diesel performance, the options that are available are many and are each equipped to do something very unique. I will attempt to address all of the most popular diesel performance modifications and their varied applications. Diesel performance has become the craze as of late, and has created quite a following. Diesel engines run at a high compression ratio and are capable of great economy and astounding power.



Without debate, the diesel performance chip and diesel performance module are the most popular diesel performance modification out there. By adding a chip, tuner, or module. The diesel engines, by enhancing injection timing, line pressure, the duration that the injectors are held open, or just by dumping more fuel are able to create another 25 to 200 horsepower. That is after a fifteen minute install that doesn’t require you to pay a mechanic or have you diesel truck or diesel car out of commission while it is being worked on by the mechanic. They are easy to install, and can be installed by most individuals with limited knowledge of the workings of the diesel engine. Most diesel performance chips and modules these days come with a monitor or digital gauge set up to monitor the new working levels of your diesel truck or car. The diesel performance chip and module have won the diesel performance market over hands down.

The next two items that I will address together are the cold air intake and the exhaust system, both of which move air. Getting air into the diesel engine is just as important as getting exhaust out of the engine. The cold air intake includes a high flowing filter, some of which are able to move up to 300% more air than the stock filter. More air into the engine helps a higher percentage of the fuel to be combusted which creates more power and better economy due to it not going out the tail pipe in a black cloud. On the other hand extreme fueling modifications should not be made if there hasn’t been sufficient accommodations made to get the exhaust out the back end. The reason a mandrel bent exhaust, higher flow exhaust, or larger diameter exhaust is so important is because when you increase power you generally increase heat. Without a way to get the back pressure to move along and decrease heat, engine damage could be the result.
