Dusterhoff Racing DT877 TRX Power Package

The Dusterhoff Racing DT877 TRX Power Package is a Max Effort pump gas performance package engineered specifically for the 2021-2024 Ram 1500 TRX powered by the factory supercharged 6.2L Gen 3 HEMI Hellcat engine. Designed for enthusiasts looking to push the limits of the factory combination while retaining outstanding street manners, the DT877 package combines carefully selected hardware upgrades with Dusterhoff Racing’s proven remote tuning strategy to produce approximately 100 wheel horsepower over stock using 91 or 93 octane pump gas only. Rather than guessing which modifications work well together, this complete package provides a tested solution that delivers repeatable performance, excellent reliability, and impressive acceleration. Whether you’re building a fast daily driver, towing with confidence, dominating highway pulls, or enjoying weekend drag strip outings, the DT877 package transforms the driving experience without compromising the everyday usability that makes the TRX so versatile.

The foundation of the DT877 package begins with the Dusterhoff Tuning Upper Pulley Kit, which increases supercharger speed to generate additional boost while maintaining factory-like drivability. To safely support the increased airflow and horsepower, the package also includes upgraded high-flow fuel injectors that provide the additional fueling capacity required for higher power levels. A heavy-duty supercharger belt is included to maintain reliable belt grip under increased boost conditions, while the 180-degree thermostat helps reduce engine operating temperatures for improved consistency during repeated hard acceleration. Every package also includes PCM Unlock Service, HP Tuners RTD with Credits, and a Smart Access Cable, allowing Dusterhoff Racing to remotely deliver custom engine and transmission calibrations tailored specifically to your truck and its modifications.

The true advantage of the DT877 package lies in its complete system approach. Every included component has been selected to complement the others, allowing airflow, boost, fueling, and calibration to work together seamlessly for maximum performance. Drivers can expect dramatically improved throttle response, significantly stronger mid-range torque, harder top-end acceleration, and quicker transmission shifts thanks to Dusterhoff Racing’s custom engine and transmission tuning. The custom calibration refines ignition timing, boost control, torque management, shift scheduling, and throttle mapping to maximize horsepower while maintaining excellent drivability and reliability on premium pump fuel.

The DT877 package also creates an outstanding foundation for future modifications should even more performance be desired. The upgraded fueling system and optimized calibration support future additions such as larger throttle bodies, ported superchargers, flex fuel conversions, heat exchanger upgrades, long tube headers, and additional engine modifications. Developed from years of real-world Gen 3 HEMI tuning experience, the DT877 delivers dependable performance gains while maintaining the confidence owners expect from a professionally engineered package. Please note: Unlocking the factory TRX PCM requires the suspension height to be recalibrated using dealer-level software following installation. Installation is not included.
