It is important to know that we tune the engine through the actual vehicle ECU. We are able to change the entire calibration and not just individual sensors.

  • Changed Rail Pressure
    • Better Fuel delivery
    • Increased power
  • Changed Boost Pressure
    • Increased performance
    • Less visible smoke
    • Reduces fuel consumption
  • Improved EGR system
    • MAXIMIZES fuel economy
    • MINIMIZES EGR hardware failures
  • Modified Main Timing in normal driving conditions
    • MAXIMIZES fuel economy
  • Change pilot injections
    • Maintain low engine noise
  • Governing systems
    • Enhance driveline stability
    • Reduce vibration
    • Better throttle tip-in response
  • Eliminated brake switch torque Limitation due to customer complaints
    • Can now press brake and throttle at the same time with no torque cut
    • Effective for off-road
  • Linearized fuel gauge to have each quarter tank approximately equal to 5 gallons
  • Adjusted EVIC fuel consumption calculation to be more accurate
  • Lowered viscous heater shut-off threshold to increase fuel economy in winter driving, while still maintaining a quick warm-up for cabin heat
  • Provides a linear throttle progression and minimizes turbo lag
  • Electric fan will turn on when transmission fluid temps increase beyond normal operating temps, this helps to keep trans temps in check in all driving conditions and especially during towing
  • Maintains latest production part number so dealers will not arbitrarily change calibration during routine service
