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

RapTorq High Performance ECM
proprietary & copyrightedRapTorq ECM was engineered over a 22 month span
with specific testing and development by our in-house Predator Motorsports
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
Power increased by 64hp & 79ft/lbs of torque providing
Rapid Torque & Horsepower gains!
