Predator Motorsports Hummer H1 Alpha Duramax RapTorq Computer Upgrade
141hp and 206ft/lbs of Torque!
Our unique proprietary & copyrighted Predator RapTorq 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 141hp & 206ft/lbs of torque providing Rapid Torque & Horsepower gains!
