Add power and fuel economy to your L5P Duramax with the most trusted name in diesel performance, Banks Power.

Stop the competition dead in their tracks with the Derringer Tuner. Banks delivers 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 six switched settings. Level 6 produces Best in Class performance that knocks you back in your seat. The Level 3 setting is for work use and has great mid-range feel. When running Level 3 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 the 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 Banks' microprocessors to talk with the vehicle. On top of that, 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.

How the Derringer does what it does, and why. - There's no easy way to make more power for your daily driven L5P with GM's ECU and factory turbo, no magic flash or special "chip" available. Banks had to go the tuner route, and making an inline tuner for your truck was no easy task. Banks has almost a thousand man-hours into Derringer development. Fortunately, they've been making tuners for 20 years, so it was all in a day's work.

The Derringer is a plug-and-play microcomputer designed for easy installation, it's waterproof for convenient under hood mounting, and connects to the iDash 1.8 Super Gauge for the ultimate in information and power selection, unlocking three additional power levels.

AutoRate - Unlike the fixed tuning used by others, the Derringer calibration is continuously adjusting to provide you the peak possible performance under every driving condition. By utilizing the power of the OBD-II data, the tuner intelligently fine-tunes its calibration on the fly without you having to change its power level.

  • Exhaust Gas Temperature (EGT) - The Derringer senses your engine's EGT and intelligently modulates fueling to maintain a safe maximum EGT, protecting your turbo and engine.
  • Altitude compensation - The Derringer senses ambient air pressure, controlling the turbocharger to maintain added boost and power as altitude increases.
  • Diesel Particulate Filter (DPF) Regen - The Derringer tuner constantly monitors your DPF regen status and will optimize its calibration to ensure the DPF regen process completes successfully.
  • Accelerator Pedal Monitoring - The Derringer senses accelerator pedal position to roll in additional power progressively, optimizing part-throttle fuel economy and giving max power when you ask for it.
  • Coolant Temperature Monitoring - The Derringer senses coolant temp to control added power. During warmup, no power is added below 120° F, then power is ramped in and fully available above 150° If the coolant overheats for any reason, the Derringer starts removing its power at 230° F and additional power is totally removed if you exceed 240° F.
  • Full Power Timer - If set on Sport level, the Derringer allows for 30 seconds of wide open throttle before transitioning to the recommended power level for sustained tow/haul. (Our research has shown that the stock L5P when at full power will hit 1450° EGT and after a minute or so will pull out fuel to cool things down. So, we do the same thing.)

TransCommand Active Transmission Safety System - In addition to AutoRate Adaptive Tuning, the Derringer utilizes key engine and transmission parameters to enhance shift performance and improve the longevity of your transmission. Because the competitors lack the essential OBD-II data, they always add power at wide open throttleno matter what! This can cause excessive transmission slip, torque converter clutch slip and even 170 HP engine derates in order for the transmission to complete the shift. This harms the overall performance and degrades your transmission. The Derringer is meticulously calibrated and extensively tested to properly modulate power during shifting, optimizing performance and safety.

  • Intelligent Shift Tuning - The transmission shift request signal is monitored to optimize the power level prior to the shift protecting the transmission, increasing shift speed and avoiding ECU power derates.
  • Boost and Fuel by Gear - Gear based calibration allows for optimum traction and performance
  • Torque Converter Clutch Slip Monitoring - The Derringer adjusts to modulate TCC slip to safe levels.
  • Transmission Slip Monitoring - The Derringer adjusts calibration to modulate transmission slip to safe levels

ActiveSafety - The Derringer is the only tuner on the market to include Active Safety, an active failsafe system that utilizes bypass relays to smoothly transition your vehicle to stock power levels in the event of any trouble signs in the Derringer. The system constantly monitors various parameters at over 50 times a second to ensure that everything is operating as it should. If any competitive tuners lose power or fail in any way, they will instantly trigger a "limp home" mode where all power is lost and the vehicle dangerously slows to a crawl. If the same fault condition occurs to the Derringer it will gracefully remove its additional power and return to stock power levels without a hitch.

  • Internal self-diagnostics checks health of the system 50 times per second
  • Monitors MAP and FRP signals for out of range condition (disconnected or short circuit)
  • Watchdog timer constantly monitors CPU activity
  • Active safety engages if 12-volt power is lost to the Derringer tuner

Amazingly Tough!
Style: Whale
This is one of our pup’s favorite toys, so much so that we always have a couple around. So far, our very-active, very destructive, deaf mixed-breed puppy has only managed to destroy one. And it was the plushie that failed, not the mechanism. Only reason I subtracted a star is that I’ve gotten a couple where the sensitivity is set WAY too high, as in, maybe it’s cosmic rays, setting it off? But other than that, great toy for a dog with high prey-drive.

Durable tug toy that our pitbull absolutely loves
As soon as I pulled this toy out, our pitty saw it and immediately wanted to play. Tug is her absolute favorite thing to do, and she is crazy about this one. She constantly looks for anyone willing to play with her. That makes me really appreciate the grip loops because they keep our hands comfortable during the tug sessions making it easy to play with her. Our house is also run by an 8 lb Chihuahua who is definitely the alpha. Believe it or not, our big pitty is scared of the little dog and just lets her steal the toy away. She just patiently waits and grabs it back the second the Chihuahua loses interest. The size is great as both dogs can get good bites on it for secure hold. We have had it for a month now, and it is holding up perfectly without any real damage. Best of all, our she still enjoys it just as much as she did on day one. I really like that it is made in the USA from BPA and latex-free materials. It cleans up easily in the dishwasher and even floats when we take it down to the ponds. --- For anyone interested, the exact product I purchased was listed as: Wagalicious, Tuggfinity, Lime The ASIN for the version I received was:

Fun Toy for Large Dogs, but Hard to Grab from Flat Surfaces
I gave this to a large dog to see how it would hold up during play. He really enjoys it and stays engaged with it, especially during active play sessions. The material feels durable enough to handle a bigger dog’s strength. It’s bright and easy to spot, which helps when playing outdoors. It’s clearly designed for interactive play. One thing I noticed is that it can be a little difficult for him to pick up off the ground. The shape doesn’t give much to grab onto when it’s lying flat. Once he gets it, he enjoys it, but getting started can take a second. It’s still a fun toy, just something to keep in mind. Works best when tossed or handed to them.
