Inappropriate use of the Sport Tune

  • Too much power for towing without the proper gauges
  • This tune should only be used during sanctioned competition and or on private property
  • Enough power for an irresponsible driver to damage his truck
  • Lending your truck to someone not experienced with driving a tuned truck or weak or average driving skills
  • Installing Sport as a single tune for frequent use without the proper supporting modifications including:
    • Low Pressure Lift Pump
    • Fuel Sump or equivalent upgrade
    • Transmission Tuning
    • Cold Air Intake
    • Exergy Fuel System Saver or Upgraded CP4
  • We recommend using Sport in our Switch on the Fly for occasional and appropriate use for our typical customers.
