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!
Proof of a higher power.
Calibrated for sport applications, Six-Gun is a performance junkie that adds +128 hp/+345 lb-ft. With its comprehensive CleanTune Technology and change-on-the-fly power, Six-Gun with Speed-Loader rockets you from 0-60 mph 33% quicker and in 36% less distance than stock ... without adding black smoke!
Power boost with Speed-Loader upgrade.
Speed-Loader punches up Six-Gun's best gains to +155 hp/ +385 lb-ft and provides temp-limiting safety (pyrometer gauge recommended).
All gains measured at the rear wheels, with recommended airflow improvements.

Jamie of Brownstown, Michigan, installed a Six-Gun Diesel Tuner, Speed-Loader and a Monster exhaust on a Duramax LB7 with a 6.6L turbo-diesel
I’ve had my truck now for about 5 years. The day I picked it up from the dealer I dropped it of at the custom shop. It’s been through 3 lift kit changes and 4 different tire and wheel packages. I’m real picky on the stuff I like and until the last lift and rims and tires were on, I wasn’t happy. Now all I had to do was drop in a Monster exhaust, an intake and a bad azz chip but no one had a chip that was worth the money for the problems they were handing out. I like Banks products and love the R/D they put into them, so it was only a matter of time to see that they once again came out with another awesome product for us to utilize.
So I waited till the time was right and ordered my Six-Gun Tuner and Speed-Loader. Now I have had previous chips and stacked computers but pump the brakes on that $#@%. This new product you guys have out now is intense. It’s a great combo and it’s a great feeling knowing that that little anodized aluminum box is under that dash taking care of me, whooping all those other (step children) chips as well as taking care of my truck. I have a few friends that have dumped a lot of money into their trucks but as I pass them up, I don’t let them know I have barely any money into mine. I just let them keep purchasing their catch-up kits.
It’s a good feeling guys. Thanks for being #1 like you are. Take care and hope to see more stuff soon.

Ted of Williamsville, New York, installed a Six-Gun Diesel Tuner on an ’01-04 Duramax LB7 4X4 crewcab with a 6.6L turbo-diesel
Wow—awesome power!! I love this system--and so do my 2 young boys (ages 5 and 8)--"Give it some boost, daddy!"; "Smoke 'em out, daddy!" This system is making other vehicles on the road look like four cylinders!! I took it to my local racetrack (unfortunately, only 1/8th mile), but seemed to embarrass a Mustang GT that I was up against. Turned a 9.7 flat on the track--darn good for a 6,000 lb diesel pickup 4x4 crewcab with stock tires!! No laughing after I did my race! Thanks for making a killer product!!

I pull a 12,000 pound construction trailer with my GMC 6.6 D/A 2500HD. I have installed the Six-Gun, Speed-Loader, and [Monster] Exhaust. WOW!! I recently towed 2,200 miles from Florida to Indiana and back. Mileage is way up. Exhaust temp is way down and the torque is Unbelievable. Without the trailer and just with a little spool up on the brakes at a red light, this thing will smoke just about any production street car. This is way more fun that any muscle car I have ever owned over the last 35 years. Thanks for your great products.

Heather of Surrey, British Columbia, Canada, installed a Six-Gun and a Speed-Loader on an ’02 GMC Crew Cab Duramax 6.6L turbo-diesel
I've been a GM girl all my life & get razzed a lot by my forever FoundOnRoadDead (FORD) friends. Early last year I was finally able to obtain the truck of trucks: an ‘02 GMC Crew Cab short box 6.6L turbo diesel. I call her Cuda because she just eats everything up in her path. To date we have beaten three 5L mustangs, one Harley Davidson edition and any other diesel who dares to try keep pace. We also got a mention on the Fun In BC's 4x4 club site for being the truck that made it furthest up the snowy mountain. When others made fun of my truck for being too large, I just sat back and asked if they wanted a tow up to where I was or just admit that my truck was king for the day. No matter if it's out in the bush or playin’ in the mud, cruising the streets or towing (anything), Banks gives that extra edge separating the girls from the boys with baby toys … yet remaining the quiet diesel I take so much pride in. I'm seriously considering taking up racing at our local track because I just can’t get enough of the vast improvements the Banks products have made to my baby. In fact, I went by Sport Trucks Unlimited where I purchased my Banks products to inquire about the Monster exhaust package and the boys told me they have done about 6 more Banks installations since my truck because people liked what they saw. Thanks Banks for making every drive a memorable experience.

I bought my new K2500 Crew Cab because I had just out-grown my old 1/2 ton. My business had expanded so much that my old truck was getting tired. I have always been a GM man and was getting so tired of the "Power choke" and "Wait, I'm Cummins" boys bash the DuraMax. I started to look at diesel "hop-up" products. I went with Banks because you are known for your milestone diesel enhancements with over all concern for safety and dependability. After the install I was shocked with the results that were achieved. I went out to show off my new toys, and found that even the other "chipped" diesels could not keep up! I wear my Banks stickers with pride because all the other guys are spending more money on other companies’ products trying to catch me (us). I wish they would only listen and call BANKS!

Andy of Ceres, California, installed a Six-Gun Diesel Tuner and a Speed-Loader on an ’01-04 6.6L Duramax LB7 turbo-diesel
Let me tell you...you are the bomb! And that’s a good thing. I tried some of the others we won’t name, but they didn’t make me as 'HYPER' as yours. I've got nothing but good to say about BANKS, and I don’t have to brag—the proof is in the pulling. You can’t believe what torque can do!
I'm a farmer and you know we always pull more than we should. This sucker I think has more power when you hook up the trailer. I love it. Thanx!
“Hey, what more can you ask of a product? More power, better mileage. It sounds like a good combination to us.”
