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 adds 43% more horsepower and torque than stock without adding black smoke. This is tire-shredding, scenery-blurring power that keeps its cool while rocketing you from 0-60 mph 20% quicker than 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!
All gains measured at the rear wheels.
Test vehicle: 2006 Chevy Silverado 2500, 4WD, crew cab short bed, automatic transmission.

David D. of Orlando, Florida, installed a Six-Gun Diesel Tuner and PowerPDA Vehicle Command Center on an ’07 Chevy Silverado with a Duramax LBZ turbo-diesel
Down right bad a-- system. I have an ‘07 Chevy Silverado classic with the LBZ motor. At first I purchased the Edge Evolution. "Only one available at the time." Good product; don’t get me wrong. But then I installed the Six Gun with the in-cab Power PDA. At first I thought it felt about the same until I realized there was one more setting called SL. "Oh Hell Ya!" The next comment I would like to use to describe the feeling it gave me is too graphic and unprofessional. "Holy SSSS"—well, you know. Without any doubt, if you are thinking of the Banks System … Thought Over. The choice is easy: Banks. You guys make a kick a--product. Thank you from Sunny Florida.

Only one problem - power is addictive!!
Thank you for a well thought out and engineered product that delivers everything as advertised and more. Your website and print literature is informative and fact based. Your sales staff is courteous, professional, and know the importance of asking probing questions and following up. Everything adds up to a flawless buying experience.
Now the fun details. I started off by first installing the Ram Air and Monster Exhaust from the 6-Gun Bundle on my 2007 LBZ Duramax to establish a baseline. I drove my truck for a few hundred miles and then had the 6-Gun tuner installed. It was an exercise in restraint in slowly dialing up the power to allow the stock Allison transmission time to adapt to the power increases, but it was well worth it. The first time I stepped on it hard on the Speed Loader level was a blast! I still grin when I think about it. The Power PDA is my favorite feature. The guage displays, on-the-fly adjustments, and OBDII code reading/clearing are awesome! I'm sure your products will deliver this for the lifetime of my truck. The quality shows! Only one problem - power is addictive!! Time to upgrade the stock Allison and unlock even more Duramax power.
Thank You again to you and your staff. Job(s) well done.

Unbelievable fit, finish and performance
My truck is an extended cab truck with a utility body and a lumber rack. Unloaded it weighs in at 7000+ pounds. Add my tools and materials and this truck was not exactly a barn-burner even with the Duramax engine...
Banks has been under my skin for more than 25 years now, so with the purchase of a Duramax Diesel I thought the time was right.
Forget the massive performance increase for a minute. Let's talk about fit and finish.
I removed the OEM exhaust and installed the Banks system in 20 minutes total. Mind blowing. I did not need any other parts than what the kit included.
Cold air intake: 15 minutes start to finish.
Again; unbelievable.
OK, OK. Performance is through the roof. My buddies refer to the utility body work truck as "white lightning".
Total and complete sleeper. Blows the doors off most things with four wheels while turning over at only 2500 RPM.
Thanks Banks. The truck is a true reflection of the quality and performance your product brings.
