Unleash the true power of your Duramax engine. The Derringer diesel tuner from Banks Power unlocks up to 61 extra horsepower and 112 lb-ft extra torque! When passing cars on the highway, you will be 13% quicker from 50-70mph!

Derringer is dyno calibrated to use multiple data inputs such as throttle position, rpm, vehicle speed, AFR, knock, coolant temperature, and EGT, just like your engine's ECM. It actively and safely optimizes calibrations in real-time thanks to its OBD-II connectivity. No competitive tuner does that.

Derringer has 6 levels, adjustable on-the-fly using the iDash (you can select an iDash above). Level 6 produces best-in-class performance. Level 3 is designed for work use and has a great mid-range feel. When running Level 3 with a loaded truck and/or pulling a trailer, your on-ramp merging speeds and passing times are greatly improved.

ActiveSafety health monitoring circuitry keeps an eye on the vehicle and the module itself. It checks its health 100 times a second. If it detects an issue, the Derringer instantly bypasses itself, sets a device diagnostic code, and seamlessly returns the truck to stock power. Plus, Derringer's special coolant temp monitoring prevents power addition when the engine is too cold or overheated. The Derringer also auto-adjusts power if knock occurs due to bad fuel. Maximum safe power is all automatic with a Derringer — you just choose your preferred power level and enjoy the ride.

Good quality
Size: Large, Color: (035) Steel / White / Black
These are a bit thicker then a compression sock and they come up higher on the ankle than a no-show sock normally does. They are very comfortable and soft.

Finally found a good set again.
Size: X-Large, Color: (001) Black / Black / Castlerock
I’m picky on socks, any they always have to be Under Amour. These are top notch, super padded but also temperature regulating, feet don’t sweat when wearing, and I can tell in the winter they’ll stay the right temperature. They also fit great. Purchasing more.

Best Quality Socks & Great Thickness Plus Comfort
Size: Medium, Color: (001) Black / Black / Castlerock
I love these. They do not slip away from foot. The value for a good pack of socks was worth it. Has a good thick quality. They look clean and nice. Their stretch is good to get on and then molds to foot. Have noticed these socks have changed two times since buying. First they were slightly lighter color gray- then a darker gray but both had good quality and thickness. I am sure these are very durable but unfortunately I can not speak fully to this as the horrible steel toe shoes I have to wear rip everything apart. But if I had good shoes and everyday use of these I know they would stay good for so much longer than 6months.
