Stops the competition dead in their tracks. Results in our torque and power gains across the full operating rpm range, starting right off idle and marching to the shift point in each gear. Derringer is dyno calibrated to use multiple data inputs such as throttle position, rpm, vehicle speed, AFR, Knock and coolant temperature, just like your engine's ECU. Its microprocessor based electronics are able to actively and safely optimize calibrations in real time. No competitive product does that.

Derringer has three switched settings: Stock, Plus and Sport. Sport produces Best in Class performance knocks you back in your seat. The Plus setting is for work use and has great mid-range feel. When running Plus with a loaded work truck and/or pulling a trailer, your on ramp merging speeds and passing times are greatly improved.

The electronics are molded into a waterproof connector, which is easily concealed and communicates using B-Bus (Banks Bus) with other devices such as our iDash 1.8 Super Gauge/Control Center. The Derringer connects in line with the Throttle Inlet Pressure (TIP) and Manifold Absolute Pressure (MAP) sensors. But, unlike others it also connects to the vehicle's OBDII diagnostic bus connector. A CAN (controller area network) transceiver chip communicates with OBD or B-Bus allowing our microprocessors to talk with the vehicle. And, Derringer's special coolant temp watchdog 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 setting.

 

The Banks difference when it comes to L5P POWER!

The Derringer tuner — When it comes down to it, you want a real L5P tuner. You want something that makes big power and doesn’t kill your truck. After all, you just spent a lot of money on that beast. The Banks Derringer L5P tuner is the only option you should be plugging into your truck. Look, the other guys claim big numbers and we call bulls—t! We tested every other tuner on the same dyno, same day, same weather conditions, with the same technician… Same damn test, period! There’s only so much you can do by just intercepting the fuel rail pressure sensor. That’s where all the others fall short. The Derringer is the only tuner that actually utilizes your truck’s ECU to make intelligent calculations!

Nice feel
Special Size: Two Pack, Size: Medium, Color: A-wine Red/Dark Grey
I’m 5’8”, trim and athletic build. The sleeves are a tiny bit tight and would be unpleasant on a warmer than expected day, but for a cool day just fine. Nice fit. Feels pleasant to the touch.

Good fit, light weight, very comfortable
Special Size: Two Pack, Size: X-Large, Color: Black/Army Green
I've purchased several of these now and overall they seem like a decent buy for the price. They are very light weight and seem to retain their shape and avoid wrinkling when hung to dry after washing. Despite never seeing a clothes dryer however, the black variant still pilled up a bit after moderate use. There seems to be some variation in sizing: all the black and olive colored ones seem pretty consistent but the gray run small and the blue just a bit large (all purchased in XL, me at 6'3 and 225#)

Great with a great price
Special Size: Two Pack, Size: X-Large, Color: A-blue/Army Green
First off. I am female 5’10”. I thought the extra large fit great. The material is very soft and light. I think they’re warm though. I just washed them for the first time yesterday with dryer. Air dry. I’d like to see after a couple washes and know how the dryer affects it.

Great products, Great seller!
Special Size: Two Pack, Size: Medium, Color: Black/Dark Blue
I have ordered over $600.00 worth of goods from this seller. Every single purchase has been exactly as advertised. The gym clothing is made with quality materials and have held up great thru my 5 day a week workouts. I have also ordered some of their fitted shirts to wear with slacks and jeans. And again all the items are extremely well made, fit as expected, and are made with quality materials. I would highly recommend purchasing from this seller. The have never let me down.

Wide, feminine neck
Special Size: Two Pack, Size: Medium, Color: Black/Army Green
I ordered Medium, as I usually wear. I’m 5’11” 175lbs. The neck was very wide and cut semi/deep. It looked like a woman’s workout shirt. The material looks and feels nice, and other than the neck it fit true to size. I returned it because of how they fit in the neck.
