Six-Gun Diesel Tuner W/Switch 06-07 Chevy 6.6L LLY-LBZ Banks Power

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 safeguards to Six-Gun so it won’t exceed those limits. As a result, Six-Gun thrashes challengers, not your truck! Airflow upgrades recommended.

Proof of a higher power.
Calibrated for sport applications, Six-Gun is a performance junkie that adds +100 hp/+195 lb-ft. With its CleanTune Technology and 6 change-on-the-fly power levels, Six-Gun rockets you from 0-60 mph 19 percent quicker and in 36 percent less distance than stock ... without adding soot!

Upgradeable options include airflow components to build a complete engineered power system. For best Six-Gun Tuner performance, Banks always recommends airflow improvements.

All gains measured at the rear wheels, with recommended airflow improvements.
