Calibrated for sport, Six-Gun is a fully engineered diesel tuner with an unmatched combination of power, safety and versatility. It delivers pavement-shredding best gains of +115 hp and +206 lb-ft at the rear wheels; has six change-on-the-fly power levels; is Stacked for Power® to tune pulse width, timing and fuel pressure; and has exclusive AutoRate® and ActiveSafety® engine and transmission safeguards.

With Banks iDash DataMonster 1.8, you add enhanced monitoring, data-logging and simple control. Monitor data your vehicle's gauge won't show you, and real values that your vehicle masks. Instant real data to keep an eye on your engine, not the inaccurate filtered data that the manufacturer shows you that can sometimes lead to failure. And log that data to see how everything is running. In fact, you can log continuously until you run out of disk space (over a month straight with a 4GB card).

  • Has 6 change-on-the-fly power levels and is Stacked for Power.
