Greater than the sum of its parts, the Banks PowerPack for the 2020-2023 Duramax L5P is a cohesive system that unlocks your truck’s full potential. The PowerPack combines engine tuning, data monitoring, airflow improvements, and cooling to deliver monumental continuous power, improved durability, lower exhaust gas temps (EGTs), and maximum fuel economy.
Experience quicker 0-60, easier freeway merging, and effortless towing while removing factory airflow restrictions for maximum sustained engine efficiency, power, and fuel economy.
The Derringer is dyno-calibrated to use multiple data inputs such as throttle position, rpm, vehicle speed, AFP, 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 while providing huge performance gains, all while keeping your factory ECM happy, temperatures under control, and transmission safe.
No competitive tuner does that.
Much more than just an On/Off throttle booster switch, PedalMonster fills the dip in your factory pedal map and restores the fun responsive feel of a linear cable throttle.
Unlike conventional cable throttles, modern electronic throttles are not linear. Part-throttle drivability is often dampened as a means to stretch fuel economy, giving a mushy and unresponsive feel.
PedalMonster puts the fun back into driving.
With a simple clean look, iDash® Stealth Pods are the perfect mount solution for 52mm iDash® gauges and engineered to withstand, heat, cold, and UV exposure for the life of your vehicle.
Press-and-go friction fit requires no screws or tape to mount the iDash®— just slide in your gauge, and twist to clock it level.
Designed with an optimized viewing angle using your factory your A-Pillar to minimize eye movement while driving.

The all-new Ram-Air cold air intake system's large organic shape eliminates all restrictions and turbulence to the turbo. The radical new design allows for a massive 58% gain in Mass Air Flow over the stock system.
The oversized Big-Ass filter has greater dust capacity giving you more miles between services and flows freely long after stock and competitors are clogged with debris.
The Patented Banks Air Mass Control Module allows our engineers to design past previous physical limitations for a truly next-generation intake.
Banks oversized charge air cooler pipes and pair of unique billet adapters results in less boost pressure loss from turbo to intake manifold.
With a 26-45% improvement in airflow, your turbo can spool faster and sustain boost pressure with less wasted energy and heat.
Banks Boost-Tubes allow your engine, and specifically your turbo, to work less hard in compressing intake air; this maximizes horsepower delivery and throttle response while reducing engine stress.
Banks patented negative back-pressure SideKick tip virtually eliminates back-pressure after the DPF. With a side-draft rocket nozzle-like tip, exhaust gasses are literally sucked out of the end of the exhaust.
With pressure sensors installed, this negative exhaust pressure resulted in an impressive 9% reduction all the way back to the turbo inlet.
With the stock exhaust nozzle measuring 2.85-inch compared to the Monster Exhaust's massive 5-inch outlet, the Banks system offers a 192% greater flow area than stock.
The Monster Exhaust boasts 89% less backpressure than stock at the DPF and 9% lower at the turbine inlet, leading to more power and increased fuel economy.
The Monster Exhaust also provides a 15% reduction in exhaust temperature two feet behind the tip during regen!
Unlike the stock Duramax exhaust, which directs a prolonged jet-like blast of super-heated exhaust gas directly at anything being towed, the Monster Exhaust is aimed out to the side of the truck.
This allows ambient air to diffuse the heated gas, eliminating the risk of melting a trailer, which has been reported by many Duramax owners.
Banks Ram-Air® differential cover extends lubrication life, retains fuel economy, and rejects heat faster than any other cover on the market.
Thanks to its superior fluid and aerodynamics, the Ram-Air® Cover out-performs stock and flat-back high-capacity covers and does so with less lubricant.
