One approach some owners consider is upgrading or removing restrictive emissions components to restore airflow and improve performance. For instance, a cummins dpf delete kit can eliminate certain filters that reduce backpressure, which some say improves fuel economy and horsepower while simplifying maintenance. Of course, it’s important to understand local regulations and warranty implications before making changes, and professional installation is highly recommended to ensure the engine stays healthy and compliant where required. Proper tuning alongside any modifications also helps maximize benefits and prevent potential long-term issues.
