The Cummins 6.7L diesel engine is a workhorse among engines. It's known for its inherent power, durability, and lifespan. This engine is a great option for your truck if you regularly need to haul, tow, or put other demands on it. However, it's not without its capacity to enhance its operation. With the right planning, you can significantly improve the performance of your Cummins engine beyond the stock statistics.
Is Tuning Worth It?
Engine tuners are a great investment when you want to personalize the performance of your engine. You can modify all sorts of things with an engine tuner, from the ignition and injection timing to the performance of the transmission. In fact, the transmission is the best place to focus when you're going to tune a Cummins 6.7L engine. You can adjust the shift points and even create a smoother, more consistent transmission response.
Just remember that, when you tune the transmission, you need to drive it accordingly. Try to avoid being heavy on the engine, rapidly accelerating, or maintaining too high of RPMs when you've tuned the transmission for lower, slower shifts.
Should You Change The Air Intake?
The factory air intake on a Cummins 6.7L engine is often restricted to keep the airflow into the engine heavily regulated. When you upgrade your factory intake to an aftermarket cold air intake, you improve airflow to the engine, which will then help improve your fuel economy.
Many people talk about power and response gains from new air intake installation. While you might see some minimal improvement in engine power, it won't be anything to write home about. The biggest gain from this improvement is to cut your fuel costs because it improves the efficiency of the engine.
Can You Upgrade The Intercooler?
The intercooler is an essential part of the air temperature management for the Cummins engine. However, because of where the stock engine has capacity for the intercooler, the stock unit is fairly small. If you want to be able to really improve your engine's fuel economy, you should install an aftermarket intercooler with greater cooling capacity. That way, you're getting cooler air through the engine, which helps to improve engine fuel efficiency and general performance.
