Dusterhoff Racing DT997E Trackhawk Power Package

The Dusterhoff Racing DT997E Trackhawk Power Package is the ultimate bolt-on performance solution for 2018-2021 Jeep Grand Cherokee Trackhawk owners who want to extract maximum performance from the factory-supercharged 6.2L Gen 3 HEMI. Designed using years of real-world testing and calibration experience, this complete package combines increased supercharger boost, upgraded fueling components, flex fuel capability, and Dusterhoff Racing’s custom tuning to create a balanced combination capable of delivering massive horsepower gains without sacrificing reliability or everyday drivability. Instead of piecing together individual components and wondering if they’ll work together, the DT997E package provides a complete, proven system engineered specifically for the Trackhawk platform. Whether your goal is dominating the drag strip, improving roll-racing performance, or building one of the quickest street-driven SUVs available, this package delivers exceptional results.

At the core of the DT997E package is a carefully selected group of airflow and fueling upgrades that allow the supercharged HEMI to safely produce substantially more power than stock. The included Dusterhoff Tuning Upper Pulley Kit increases supercharger speed for additional boost, while the heavy-duty supercharger belt provides improved belt grip and reliability under higher load. To support the increased airflow, the package includes high-flow fuel injectors, a JMS FuelMax Boost-A-Pump, and a complete flex fuel conversion kit, allowing the engine to take full advantage of E85’s higher octane and superior cooling characteristics. A 180-degree performance thermostat helps reduce operating temperatures, while the included PCM Unlock Service, HP Tuners RTD with credits, and Smart Access Cable allow Dusterhoff Racing to develop a custom calibration specifically for your vehicle.

The 2.64 pulley is the standard setup for this package. Opting for the 2.72 will produce slightly less power, but it will also slow the supercharger down, helping reduce the risk of potential blower damage over time.

This package is good for roughly 200 whp over stock.

With the proper fuel and supporting modifications, the DT997E package is capable of producing approximately 200+ horsepower over stock, completely transforming the Trackhawk’s performance. Drivers can expect significantly quicker throttle response, substantially stronger mid-range torque, harder acceleration throughout the RPM range, and improved consistency during repeated high-performance driving. Every custom calibration is tailored specifically to your vehicle and component combination, optimizing fueling, ignition timing, boost management, transmission operation, torque management, and cooling strategies for safe, repeatable performance.

The DT997E package is also an outstanding foundation for future performance upgrades. Whether you plan to add a larger throttle body, ported supercharger, upgraded heat exchanger, camshaft, long tube headers, or additional drivetrain modifications, this package establishes a proven platform for continued growth. Dusterhoff Racing has developed every component combination to work together as a complete system, eliminating compatibility concerns while maximizing overall performance.
