Camshafts have a major impact on engine performance. They determine how fast your diesel engine can accelerate, which is why engine specialists recommend a cam with asymmetrical profiles for the intake and exhaust lobes. This will create a wider and fatter power band.


A tuner is one of the most common diesel performance upgrades and it’s also probably the best bang for your buck. Depending on the brand and features, a tuner can increase your diesel performance by up to 50hp or more. However, there are some tuners that can void your warranty and can cause the PCM to rat out on you.

To avoid voiding your warranty, use a well-reviewed brand like Spartan, SCT or Banks. Just be sure to follow the manufacturer’s recommendations for installing and using the product. In addition, it’s important to choose a dealer that is mod friendly.
