Banks Power Six-Gun Tuner (2001-2004 GM HD 6.6 Diesel)

Tuning that doesn’t kill the host vehicle.
Many tuners reduce fuel delivery as exhaust gas temps rise. But they ignore the powertrain! Banks finds the limits of the engine and powertrain, then adds mission-critical ActiveSafety® and AutoRate® safeguards to Six-Gun so it won’t exceed those limits. Has 6 change-on-the-fly power levels. Is Stacked for Power to tune timing and fuel pressure. As a result, Six-Gun thrashes challengers, not your truck!
