DT877 Redeye / Demon / Super Stock Power Package

The Dusterhoff Racing DT877 Redeye / Demon / Super Stock Power Package is engineered for owners of 2019-2023 Dodge Challenger SRT Hellcat Redeye, Challenger SRT Super Stock, Challenger SRT Demon, and Charger SRT Hellcat Redeye who want a proven, reliable upgrade capable of delivering substantial horsepower gains while maintaining factory-like drivability. Built around the legendary high-output 6.2L Supercharged High Output Gen 3 HEMI, the DT877 package combines carefully selected performance components with Dusterhoff Racing’s custom calibration strategies to maximize power without the uncertainty of piecing together individual modifications. Every component has been chosen through extensive real-world testing to ensure compatibility, reliability, and repeatable results whether the vehicle is used on the street, drag strip, or during roll-racing events. If you’re looking for one of the best first upgrades for your Redeye or Demon platform, the DT877 package delivers exceptional performance with a straightforward installation process.

The foundation of the DT877 package is increased boost combined with precise engine calibration. The included Dusterhoff Tuning Upper Pulley Kit increases supercharger speed, allowing the factory 2.7L IHI supercharger to generate additional boost pressure and significantly improve airflow throughout the RPM range. A 180-degree performance thermostat helps reduce coolant temperatures during spirited driving, while the PCM Unlock Service, HP Tuners RTD with credits, and Smart Access Cable provide everything needed for Dusterhoff Racing to remotely calibrate your vehicle specifically for the installed components. Unlike generic handheld tunes, every calibration is customized for your exact vehicle, maximizing horsepower, torque, drivability, throttle response, transmission behavior, and overall performance.

The DT877 package is capable of producing approximately 100+ horsepower over stock when used with the recommended premium pump fuel and proper supporting calibration. Drivers immediately notice harder acceleration, increased mid-range torque, stronger top-end power, quicker throttle response, and improved overall engine responsiveness. Whether launching from a stop, accelerating onto the highway, or making a pass at the drag strip, the additional power transforms the driving experience while preserving the refinement expected from these flagship Mopar performance vehicles. Dusterhoff Racing’s tuning philosophy focuses not only on peak horsepower but also on smooth power delivery, consistent performance, and long-term reliability.

Another advantage of the DT877 package is its ability to serve as a foundation for future modifications. Owners planning to add flex fuel capability, upgraded fuel injectors, larger throttle bodies, ported superchargers, aftermarket camshafts, upgraded heat exchangers, or additional drivetrain upgrades can confidently build upon this package knowing every component has been selected with future expansion in mind. Rather than replacing parts later, the DT877 establishes a proven performance platform that grows alongside your build.
