Hummer H1 RapTorq Computer Upgrade 6.5td

102hp and 156ft/lbs of Torque!

The unique, proprietary and copyrighted programming built into our RapTorq ECM is the result of 18 months of a specific Predator Motorsports H1 Performance development team.

The research phase of the RapTorq development included a full evaluation of all available ECM programming by our competitors. Our primary goal in this program was to create superior drivability and maximum power within the GM-prescribed exhaust-gas temperature limit.

While it remains standard practice by our competitor to use only a modified, factory GM fuel-delivery curve, our RapTorq features a completely new fuel curve used in conjunction with a new start-of-injection timing curve. These are coordinated to optimize the design characteristics of the H1�s combustion chamber, providing peak efficiency and rapid power gains across the engine's entire operational range.

The RapTorq programming provides rapid throttle response, crisp light-throttle performance and strong heavy-to-full throttle power. Fuel economy is improved through all operational conditions on an average of 10-20%. Power is increased by 102hp and 156ft/lbs of torque when accompanied with our exhaust system, giving you Rapid Torque and Horsepower gains.

Each RapTorq ECM casing is powder coated silver and all screws have been replaced with Stainless Steel hardware. RapTorq will arrive at your door in a black suede lined cherry wood box and is accompinied by full color installation instructions, dyno sheet, certificate of authanticity and decals to distinguish your H1 from the pack.
