How to Get More Power from Your Cummins ISX

Want more power from your Cummins ISX engine? Start by upgrading parts like the turbocharger, fuel injectors, and exhaust system. A new turbocharger helps your engine get more air, which means better performance. Upgraded fuel injectors give the engine more fuel to burn, boosting power. A better exhaust system also helps the engine run smoother by reducing pressure. You can even adjust your engine’s computer (ECM) to fine-tune how it runs.

How to Get Better Fuel Mileage from a Cummins ISX

To improve fuel mileage with your **Cummins ISX**, follow these key steps:

**Regular Maintenance:** Keep your engine in top shape by regularly changing air filters, fuel filters, and oil. A well-maintained engine runs more efficiently, saving fuel.

**Upgrade to an Aftermarket Turbo:** Install a performance turbo from Diesel Power Source. Our turbos provide better airflow and optimize combustion, helping your **ISX Cummins** use less fuel while maintaining power.

**High-Flow Exhaust System:** Reducing backpressure with a free-flowing exhaust system helps your engine run smoother and more efficiently.

**Low-Rolling Resistance Tires:** These tires reduce drag, improving fuel efficiency with less effort from your **Cummins ISX 15** engine.

**Drive Smart:** Avoid idling and maintain steady speeds to minimize fuel consumption.

**ECM Tuning:** Adjust your engine’s settings through ECM tuning to further enhance fuel efficiency.
