Power Gain

Wheel Horsepower
Wheel Torque

Derringer has 6 power levels, adjustable on-the-fly, with a best gain of +117 hp pushing power well above 520 wheel hp to the road. Plus, the massive increase of +225 lb-ft of torque is situated right in the heart of the power band where you need it most.

Level 6 produces best-in-class performance, while Levels 2-4 are optimized for work use with great mid-range feel with a loaded truck or towing a trailer.

Derringer H.O. vs the Competition

Derringer High Output 0-60 vs Pulsar vs Stock

The Derringer High Output outruns the Edge Pulsar, using less fuel and maintaining lower exhaust gas temperatures.

Thanks to the Derringer High Output's more precise tuning between the engine and the transmission, the 0-60 distance is reduced by over half a truck length compared to the Pulsar and almost two full truck lengths over stock. That's a distance of over 35 feet.

High Output Tuned Safely

The Derringer HO maintains 10% cooler EGTs than Pulsar in our repeated tests. You do not want a tuner that adds fuel without additional air. An over-rich tune results in high exhaust temps and increased soot productions.

To maintain peak performance, EGT must be monitored and kept below 1550°F to avoid engine derate. This is when the ECM protects the engine from high temps by reducing fuel injection. In other words, the engine makes less horsepower when you need it the most. Imagine towing up a grade at altitude during the summer. The Banks Derringer-powered truck will outrun the Edge Pulsar truck when its EGTs climb and the ECM withdraws fuel to help cool the engine.

Consistent Power Delivery

The real-world benefits of powerful tuning done safely and reliably really show when you’re hauling a heavy load. At peak power, Derringer HO runs 10% leaner than Pulsar at its peak power, resulting in 6% better fuel economy.

Competitive products have been shown to over-fuel when under load which results in increased heat as well as loading up the diesel particulate filter (DPF) much quicker. The more the DPF is full of soot, the less time the engine will make full power. And, more frequent regens shorten the life of the DPF.

AutoRate® Dynamic Tuning

Diagram of Derringer High Output installation with iDash Pro
  • Exhaust Gas Temperature (EGT) — Monitors EGT and intelligently modulates fueling to maintain a safe maximum EGT, protecting your turbo and engine.
  • Altitude compensation — Senses ambient air pressure, controlling the turbocharger to maintain power as altitude increases.
  • Coolant Temperature Monitoring — Maintains safe power based on coolant temp.
    Derringer does not add power below 160°F or above 240°F
  • Full Power Timer — Allows for 30 seconds of wide-open throttle before transitioning to the recommended power level for sustained tow/haul.

ActiveSafety® Health Monitoring

Banks combines mechanical fail-safe measures to revert to stock in the event of internal failure while also intelligently adding power based on vehicle operating conditions, such as cold or hot coolant temps or knock from bad fuel.
ActiveSafety illustration

Derringer is the only tuner available with Active Safety® health monitoring circuitry:

  • Internal diagnostics checks the system 100 times per second
  • Checks MAP and FRP signals and monitors CPU activity
  • Activates in the event of failure or loss of 12-volt power
  • Bypass relays smoothly return stock power with no loss of power or "Limp Mode"

Includes iDash Powertrain Information Center

Derringer includes iDash Pro, the most advanced iDash ever. The iDash Pro Powertrain Information Center is a microcomputer that allows you to monitor and record what’s actually going on under your hood, as well as control Derringer, PedalMonster, and more. The compact device blows away the capabilities of any OBD plug-in diagnostic device and offers more functionality than instruments 5X the price.

TransCommand® Active Transmission Safety System

Closeup of transmission internals

Derringer High Output is calibrated to modulate power during shifts for better clutch engagement. Thanks to its OBD connectivity, Derringer knows when the GM/Allison 10-speed transmission is shifting gears. It reduces its added power momentarily to allow for a smooth shift. Competitive tuners have no idea or simply ignore when the transmission is shifting and continue to add power, overspeeding the transmission and causing long-term damage.

  • Intelligent Shift Tuning — Gear shifts are optimized for each power level to protect the transmission and increase shift speed while protecting against torque converter and clutch slip.
  • Accelerator Pedal Monitoring — Rolls in additional power progressively, optimizing for both part-throttle fuel economy and maximum power when you want it.

Progress Through Evolution

The iDash Pro® builds upon the foundation of the iDash Classic and adds improvements including a new high-res screen, wireless updates, expanded internal memory, 25% faster data logging, and additional features coming soon.

Torque Response Curves

PedalMonster improves take-off and mid-range punch by reshaping your vehicle's torque delivery with smooth multi-point curves and predictable throttle feel. Choose between 30 selectable Torque Response Curves: High Torque, Midrange, and High Performance, each with 10 curves.
Banks PedalMonster
Pedal Commander

By comparison, Pedal Commander and all other throttle controller boxes rely on a single point with an abrupt knee you can feel through your throttle input. This makes part-throttle drivability twitchy, difficult to modulate, and causes your transmission to hunt for gears.

Launch Trim

If you've selected an aggressive Master Torque Response Curve for maximum mid-range punch, but find it too aggressive at low speeds, choose from 5 levels of Launch Trim to soften torque delivery below 10 mph.

Exclusive Safety Features

ActiveSafety®
Launch Rate
Reverse Safety
Trans Select

There are dozens of throttle response controllers on the market like Pedal Commander, Sprint Booster, iDrive, just to name a few. Each of them claims to be the most advanced. Thanks to its OBD connectivity and patented safety features, the PedalMonster Torque Booster has very little in common with these brainless devices.

OBD Connectivity Brings Safety

PedalMonster connects to the vehicle's Onboard Diagnostics (OBD) port to access +12v and vehicle data. This reliable power source and real-time vehicle information is used to provide smooth, speed-based Active Torque Curves and important safety features.

Throttle Response Controllers like Pedal Commander draw power from the accelerator pedal circuit, often overloading the circuit and leading to dead pedal and an inoperable engine.

Dumb devices like these don't know the vehicle's speed, gear, or transmission time. In fact, they don't even know that they're in a vehicle.

Reviews

Money well spent

"The power difference even without the pedal monster is quite noticeable. But I believe I've got everything banks has to offer for my 2020 gmc sierra 2500 and I gotta say im very pleased."

— Patrick T. (5/5)

Night and day Difference!!

"I finally pulled the plug and bought the Derringer tuner for my GMC 2500 HD AT4X. My honest opinion is it’s like driving a totally different truck. I tow a 35 foot fifth wheel regularly and all I can say is Wow! I should have done it earlier! Install was straight forward and Banks install videos are top notch. Very impressive and noticeable improvement in power and throttle response❤️ Yes it’s a lot of money but the smile it put on my face made it worth it😁"

— Scott H. (5/5)

BANKS POWER BABY!

"Listen… the Derringer, Pedal Monster, and iDash Pro COMPLETELY changed the badassery of my 6.6L Duramax AT4. Prior to installing this kit, I had the CAI, Boost Tubes, and Turbo Inlet; all of which look fantastic and had improvements… but I truly believe once the Derringer went in and the Pedal Monster changed the dynamics of my gas pedal position is AWOKEN everything. I’d wager this truck is easily the fastest most powerful vehicle I’ve car had. Faster than my Harley, my Dirtbikes, you and it. I am so so happy with all my Banks upgrades I can’t shut up about it to my buddies that have diesels also. 1000% worth it; you will NOT be disappointed."

— Nicholas W. (5/5)

Loaded with Banks

"Purchase Banks tranny pan, oil pan, rear diff cover and Derringer for my 2004 GMC AT4. For the sole purpose of hauling a 5th wheel from the Grand Canyon to Anchorage Alaska and back over the summer. We are currently head back to the lower 48 and all of the above have performed perfectly through mountain passes and the very rough ALCAN highway. Tran’s temp never went over 170, oil and coolant temps remained normal and rear diff kept things cool. The derringer on level 2 gave the best gas mileage while on level three gave more than enough torq and power to pass slow semis going up the mountain passes. Could not be any more pleased with Banks!"

— chris m. (5/5)

WOW!

"I put the derringer and pedal monster on my truck which only had 300 miles on it and WOW! These products work. Will update after more time, but no complaints from me. Banks Power 💪"

— D. J. (5/5)

2024 GMC 2500Hd Duramax

"The install was very easy and straight-forward kudos to banks. As a kit it was a night and day difference. This definitely poked the bear and woke up the truck. Can't wait to give it a full testing with my 44ft 5th wheel in a couple weeks. Great upgrade so far so good."

— Sean R. (5/5)

Great for increased MPG

"This was my first Banks upgrade for my '24 2500 HD LTZ . . . install was straight forward. Instructions are well done and easy to follow. I do some pulling but half to two thirds of my use of the truck is unloaded. I wanted this package for fuel economy as I'm in Ca where diesel is $7+ per gallon. I run the Derringer on 2 (eco mode essentially) and Pedal Monster on 2 also. The truck is more responsive and smoother to drive AND I've realized a 2 MPG increase with just this package (no other modifications whatsoever). I've got about 3k miles on it now and it definitely makes a difference with the Derringer set at 4+ when towing also. I haven't done enough towing with it yet to say what the towing at 4+ does to fuel consumption. If you're looking for relief at the pump. This thing will pay for itself in a year if your going thru a tank a week. I would buy it again in a heart beat."

— Josh (5/5)

best kit I've ever ordered

"For anything. Anywhere. Instructions were clear, step by step, were actually doing the job I was doing not "similar job on different vehicle". Everything I needed was included in the kit, parts are high quality - I have never in 35 years of spinning wrenches seen a better packaged "you will not have any questions" solution than this. This should be the standard the entire world operates on."

— Joshua H. (5/5)

On the fence

"Install was simple enough. Many different settings to choose from. Truck started throwing some codes after installed. Troubleshot that for a bit, now parking brake service keeps coming on. The parking brake may or may not be unrelated but I will find out. So im on the fence for now if this was a good buy or not."

— Rey C. (3/5)

Derringer High Output

"First off, I don’t usually do reviews. The Derringer is awesome! The choice of multiple levels is exactly what I needed. After the installation, I pulled a camper from Denver to Salt Lake using level 2 and averaged 16. 5 miles to the gallon! Last week I was hauling round bales, 8 at a time, using level 3 and was not lacking any power. The combo of the Pedal Monster makes it the perfect power when I need it device. Couldn’t be happier. Thanks Gale."
