Engineered specifically for 2008 through 2010 Ford F-250, F-350, F-450, and F-550 Super Duty trucks powered by the 6.4L Powerstroke twin-turbo diesel engine, the Industrial Injection XR1 Series Compound Turbo Upgrade (Part # 479514-XR1) provides a balanced, drop-in replacement set designed to handle aggressive tuning while remaining in peak efficiency ranges.

By upgrading the low-pressure charger to a 71mm billet wheel and matching it with an optimized 58mm high-pressure charger, this setup lowers EGTs, improves throttle response, and supports robust power levels up to 750 HP under heavy loads.
