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
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
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.
