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.
