Stage 1 Wake Up Kit +64 HP

The Stage 1 Wake Up Kit for your 2003-2007 H2 will make a considerable difference to the overall drivability and longevity of your H2 Hummer. The basis of this performance upgrade is our unique proprietary & copyrighted RapTorq ECM. This kit instantly adds up to 64 horsepower with easy and simple installation! The Stage 1 Wake Up Kit provides exclusive, full range Dynamic Spectrum Tuning of air/fuel ratio, ignition advance, transmission and various other parameters for ultimate power gains and optimal mileage. Hands down the best performance gain available for the price!


• Power gains across entire power band, not just at full throttle

• Improves throttle response, acceleration, and low-end torque

• Provides performance gains up to 64 horsepower

• Simple installation

 Stage 1 – This stage is for stock or mildly modified H2 vehicles. Fuel and timing-curves are modified using lower-octane fuel and programming is designed to burn lower-octanes at peak efficiency, resulting in improved performance and optimal mileage. Drivers can use low-cost regular octane fuel for potential mileage gains, or mid-grade and higher fuel for optimal performance gains.

 **Available in Stage 1, 2, 3, & 4! Dyno tested to ensure top horsepower and drivability.

 Kit Includes:

RapTorq ECM

 Predator Black Air Intake System

 Predator Air Intake System

 Each Intake System dramatically boosts airflow for great gains in horsepower and torque. By feeding your engine more air, Predator unleashes loads of untapped potential—to the tune of massive gains in torque, horsepower, and fuel economy.

 Dyno proven gains up to 15HP!

 **Predator Air Intake System is 100% emission legal!


RapTorq High Performance ECM


Our unique proprietary & copyrightedRapTorq ECM was engineered over a 22 month span with specific testing and development by our in-house Predator Motorsports engineering team.

 During the development phases of our RapTorq ECM, our engineering team included a full evaluation of all available ECM programs by our competitors. While it remains standard practice to only modify the factory GM fuel-delivery curve. Our RapTorq ECM features a completely re-engineered “fuel-delivery curve &start-of-injection timing curve”. This design is engineered to optimize the H1’s combustion chamber providing peak efficiency and rapid power gains across the engines entire power band.

 Our RapTorq ECM programming provides rapid throttle response from light-throttle to full heavy-throttle performance power. In conjunction with power gains, Fuel Economy is also improved on an average of 10-20% throughout all operational conditions. The primary goal was to create superior drivability with a maximum power curve within the OEM GM exhaust-gas temperature limits.

 Power increased by 64hp & 79ft/lbs of torque providing Rapid Torque & Horsepower gains!
