Total power system for sport applications calibrates fuel flow to extensive airflow upgrades for tremendous power (+124 hp,+303 lb-ft) without the heat load. No airflow gridlock. Banks Six-Gun Bundle replaces the power-robbing factory airflow inefficiencies with free-flowing components that dramatically increase intake airflow and air density and expel exhaust with virtually no backpressure. Power that keeps its cool. Banks balances the improved airflow with advanced CleanTune Technology that delivers up to 54% more horsepower and 68% more torque than stock without adding black smoke. This is tire-smoking, scenery-blurring power that keeps its cool while rocketing you from 0-60 mph 24% quicker and 154 feet ahead of stock! Live long & run strong. Forget mismatched components. Run away from tuners that can destroy your engine. Everything in the Six-Gun Bundle is engineered to work together to maximize your engine's power, efficiency and durability. Six-Gun Bundle honors your vehicle by safely living within the limits of your engine and powertrain. Your Duramax will run stronger and live longer!
