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
