Banks Power Six-Gun is a performance tuner designed for diesel engines. It optimizes fuel delivery for increased power while maintaining safety through built-in safeguards and temperature limiting controls. Unlike some tuners, Six-Gun prioritizes the entire powertrain's health by adjusting fuel delivery based on exhaust gas temperatures. This approach delivers significant performance gains (up to +102 hp/+275 lb-ft) without compromising engine or transmission longevity. CleanTune® Technology ensures minimal soot emission. The Six-Gun offers on-the-fly power adjustments and comprehensive engine monitoring capabilities through compatible accessories like the Banks iDash DataMonster®. All performance figures are measured at the rear wheels, and airflow upgrades are recommended for optimal results.
