Six-Pack Powertech Chip Kits
6-Pack Multi-Program Computer Chip
  • 1994 GMC and Chevrolet Models
  • See Fitment Tab for All Applications
  • Sold Individually

    This multi-program chip gives 1994 GMC and Chevrolet 5.7L models six selectable engine calibrations at the push of a button. Programs range from all-out performance to towing and fuel-saving economy, and one setting doubles as a security mode that prevents the engine from starting.

    JET Performance 2940556P 6-Pack Multi-Program Computer Chip Features:

    • Fits 1994 GMC and Chevrolet models; see Fitment tab for all applications
    • Six selectable programs switch with the push of a button
    • Economy, towing, Stage 1 and Stage 2 performance programs
    • Security program prevents the vehicle from starting
    • Programmed for the specific vehicle application
    • Plug-in installation

    • With JET Six-Pack Powertech Chip Kits you have six individual modes that you can easily choose from, ranging from vehicle performance to a particular driving style. Select desired mode, and then use the controller's key to "lock" it (modes can't be changed without the key).

    Stage 1

    • For stock or mildly modified engines
    • Fuel and timing curves optimized for use with low octane
    • Fuel burns at peak efficiency for better performance and mileage
    • Midgrade octane is recommended for even better gains

    Stage 2

    • For performance enthusiasts (works with aftermarket intakes, mass air sensors, TBI spacers, etc.)
    • Fuel and timing curves extensively modified for use with 91 octane (required)
    • More aggressive than Stage 1 in order to gain the most horsepower and torque available
    • Requires 180° thermostat and free-flow exhaust

    Economy

    • For freeway cruising and road trips where mileage is more important than high performance
    • Fuel and timing curves optimized for efficiency using 87 octane

    Towing

    • For pulling trailers and hauling
    • Fuel and timing curves modified for use with 87 octane or better
    • Improved low end torque and mid-range passing

    Valet

    • For abusive driving protection from valet parkers, teenagers, spouses, mechanics, etc.
    • Restricts fuel delivery and governs RPM to prohibit unwanted driving

    Security

    • Built-in device can cut off fuel delivery to the injectors so the engine can't be started
