Dusterhoff Racing DT515 Power Package | 2011-2015 SRT8 392 Charger & Challenger

The Dusterhoff Racing DT515 Power Package is a complete entry-level performance solution developed specifically for 2011-2014 Dodge Challenger SRT8 392 and Dodge Charger SRT8 392 models equipped with the legendary 6.4L Gen 3 HEMI engine. Instead of piecing together individual upgrades, this carefully selected package combines proven performance components with professional custom tuning to deliver noticeable horsepower gains, sharper throttle response, and a more responsive driving experience. Whether you’re looking for a stronger street car, improved track performance, or simply want to unlock the potential hidden in your factory calibration, the DT515 package provides an easy and reliable path to more performance.

Package Includes:

AFE Momentum Cold Air Intake
180 Thermostat
HP Tuners RTD with credits
Dusterhoff Racing Custom Tuning

This package includes an AFE Momentum Cold Air Intake, allowing your 392 HEMI to draw cooler, less restrictive airflow for improved engine breathing and increased efficiency. A 180-degree thermostat helps reduce operating temperatures, allowing the engine to maintain more consistent performance under spirited driving conditions while supporting more aggressive tuning strategies. To complete the package, an HP Tuners RTD interface with the required tuning credits is included, giving customers everything needed to flash their PCM using Dusterhoff Racing’s proven custom remote tuning. The result is improved throttle response, stronger mid-range torque, optimized shift behavior on automatic-equipped vehicles, and increased overall performance while maintaining excellent street manners.

Unlike generic handheld tuners or canned calibrations, every Dusterhoff Racing custom tune is developed specifically for your vehicle and modifications. Our calibration process optimizes ignition timing, fuel delivery, throttle mapping, torque management, cooling fan operation, transmission behavior (where applicable), and numerous other parameters that factory programming leaves on the table. This allows your 6.4L HEMI to take full advantage of the included hardware upgrades while maintaining safe operation and exceptional drivability. The included HP Tuners RTD makes the remote tuning process simple, allowing customers to receive professional-level tuning without needing to visit a dyno facility.

The DT515 Power Package also provides an excellent foundation for future modifications. Many enthusiasts begin with this package before adding long tube headers, larger throttle bodies, intake manifolds, camshafts, flex fuel conversions, or additional naturally aspirated upgrades. Since the custom tuning can be updated as your build evolves, this package continues to provide value long after the initial installation. If you’re looking for one of the best performance upgrades for your 2011-2014 SRT8 392, the DT515 Power Package delivers a complete combination of airflow improvements, cooling upgrades, and professional calibration backed by Dusterhoff Racing’s Gen 3 HEMI tuning experience.
