A stock diesel truck comes with the bare essentials, so you may want to mod it. Get a boost in your diesel performance with these tips.

Did you know that approximately 75% of commercial vehicles in the truck industry are powered by diesel engines? Although diesel power is nothing to scoff at, stock trucks often don't reach the maximum levels of performance.



We've put together a brief guide that details everything you need to know about how to increase your diesel performance.

Let's dive in.

1. Update Your Truck's Computer System

The first place to start when it comes to boosting diesel performance is by updating your truck's computer system. This will allow you to take advantage of the latest technology and also get more power out of your engine. Newer trucks come with updated computer systems that are much more powerful than older models.

This is not something you should overlook, as it could be exactly what you need to take things to the next level.

2. Invest in a Cold Air Intake

Cold air intakes are one of the best ways to immediately increase the power of your diesel engine. By allowing more cold air into the engine, you'll see a noticeable difference in performance.

This is because cold air is denser than warm air, so it can help your engine to run more efficiently.

3. Get a New Exhaust System

Another great way to improve your diesel performance is by investing in a new exhaust system.

A good exhaust system will help to reduce pressure, which can significantly increase your truck's power. It's also a good idea to get a catalytic converter that will further reduce emissions.

4. Install a Turbocharger

If you're really serious about boosting the power of your diesel engine, then you might want to consider installing a turbocharger.

Turbochargers can significantly increase the amount of power that your engine is able to produce. They work by forcing more air into the engine, which allows it to run at a higher level of efficiency.

5. Use High-Quality Fuel

One of the simplest ways to improve your diesel performance is by using high-quality fuel. So, you should use a fuel that has a higher octane rating and is designed for use in diesel engines.

Through this process, you'll see an increase in power and an improvement in fuel economy.

6. Change Your Oil Regularly

Another important tip for boosting diesel performance is to change your oil regularly. Over time, your oil will start to break down and become less effective. It's crucial to do so to keep your engine running at its best.

You should also use a higher-quality oil that's designed for use in diesel engines. Not only will this help improve your performance, but it will also allow you to get the most out of the money you spent on your oil.

Low-quality oil doesn't last as long or provide as much value, causing you to spend more money over time replacing it.

Tips for Improving Diesel Engine Performance

7. Keep Your Engine Clean

It's also important to keep your engine clean if you want to see an improvement in performance. Over time, your engine will start to accumulate dirt and grime, which can negatively affect its ability to run properly.

So, it's a good idea to clean your engine on a regular basis. You can do this by using a pressure washer or simply taking it to a professional for a thorough cleaning.

8. Inspect Your Tires

Another simple tip that can help to boost your diesel performance is to inspect your tires as time goes on. Over time, tires will start to wear down and lose their grip.

This can lead to numerous issues (such as getting fewer miles per gallon), so it's important to keep an eye on them. You should keep an eye on your tire pressure.


Outside of performance, this is essential for road safety. Worn tires could inadvertently lead to accidents.

9. Get Your Truck Calibrated

If you want to get the most out of your diesel engine, then it's crucial to get your truck calibrated. This process involves adjusting your truck's computer system so that it's able to run more efficiently.

As a result, you'll see a substantial improvement in your truck's performance. The professional you work with will tell you how often a recalibration is necessary.

10. Upgrade Your Fuel Injectors

Finally, one of the best ways to boost your diesel performance is by upgrading your fuel injectors.

Fuel injectors play a critical role in how well your engine runs. Over time, they can become clogged and worn, which can lead to a decrease in how your engine runs. Even a simple upgrade could significantly improve your performance.

What Are Signs That I Need to Make Changes?

If you've noticed a decrease in your diesel truck's performance, then it's likely that you need to make some changes.

Some common signs that indicate a need for improvement include:


  • Decreased fuel economy
  • Poor acceleration
  • Rough idling
  • Excessive exhaust smoke


If you notice any of these issues, then it's a good idea to take action to improve your truck's performance.

Improving Your Diesel Performance Is Easier Than It Seems

Although it may seem complicated at first, improving your diesel performance is fairly straightforward. By following the tips above, you'll be well on your way to getting the most out of your engine. In no time, you'll notice a significant difference in how your truck runs compared to before.
