Six-Gun® Diesel Tuner & Speed-Loader®
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 +102 hp/+275 lb-ft. With its CleanTune Technology and change-on-the-fly power, Six-Gun with Speed-Loader rockets you from 0-60 mph 24% quicker and 154 feet ahead of stock ... without adding soot!
Power boost with Speed-Loader upgrade.
Speed-Loader punches up Six-Gun’s best gains to +124 hp/+303 lb-ft and provides temp-limiting safety (pyrometer gauge recommended).
All gains measured at the rear wheels, with recommended airflow improvements.

'04 Dmax exhaust/tuner: Flat Out F-----g Flys
2005-11-10
Tony of Huntingtown, Maryland, installed a Six-Gun Diesel Tuner, Speed-Loader and Monster exhaust on an ’04 Duramax 6.6L turbo-diesel
I had a Chevy diesel back in 1996 with Banks exhaust and remembered how good it was then, so I bought it again. I installed this exhaust in my garage — no lift, no jack. Off with the old, on with the new in 35 minutes. I build hot rods for a hobby and I have installed everything under the sun in the past 20 years and this was the nicest, cleanest and most precise install I have ever done! So needless to say I had a Six-Gun and Speed-Loader overnited to me the next day. There again, a simple, clean and neat install. I have to laugh every time I drive this beast.
FLAT OUT F-----G FLYS.
