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!

Proof of a higher power.
Calibrated for sport applications, Six-Gun is a performance junkie that adds +127 hp/+345 lb-ft. With its comprehensive CleanTune® Technology and change-on-the-fly power, Six-Gun rockets you from 0-60 mph 28% quicker and in 31% less distance than stock ... without adding black smoke!
