Six-Gun® Bundle

Banks iQ upgradeNo 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 CleanTuneTM 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!

LLY Six-Gun Bundle: The Porsche 944 Turbo Had Problems Keeping Up With Me

2005-07-10

Jon of Indian Springs, Ohio, installed a Six-Gun Bundle on an ’05 GMC Sierra Duramax LLY with a 6.6L turbo-diesel

Wow, Wow, Wow. Just put the Six-Gun Bundle in last night at my brother’s shop. Made some runs down a 1/4 mile street behind the shop. Wanted to make comparison on the newfound power so I ran the truck against a Porsche 944 Turbo that my brother was working on and I think I left him looking for some more power on the 944. He had some problems keeping up with me. This is the most impressive upgrade I have ever done on any of my vehicles. Thanks Banks for an excellent system.
