New L5P Tuner: Banks Derringer® for 2020 6.6L Duramax

Safest inline tuner available adds 81 hp and 144 lb-ft to Duramax L5P

Azusa, CA, February 20, 2020 – Banks Power, the exclusive worldwide distributor of the GM Duramax engine, introduces the newest member in its Derringer family of performance inline tuners. The Derringer is designed to give the 2020 L5P owner exceptional power, reliability, and safety at a competitive price.

The Derringer adds a tested best-in-class horsepower gain of 81 hp and a best torque gain of 144 lb-ft. Inspired by the “hide-out gun” of the same name, the Derringer is an easily-concealed plug-and-play microcomputer control module, designed for quick installation.

Exclusive features include Banks AutoRate® which intelligently provides optimum power by reading the vehicle’s RPM, speed, gear, exhaust gas temperature, coolant temp and more off the OBD-II diagnostics port. This data is utilized to provide both maximum performance as well as increased safety and reliability. With built-in Banks TransCommand®, the Derringer protects the transmission with intelligent power delivery for slippage prevention and smooth shifting. Banks ActiveSafety® adds a layer of protection with its self-monitoring hardware that provides automatic bypass should the unit loose power or malfunctions. This ensures power is always available to avoid dangerous limp-home conditions caused by other tuners. In addition to reading over a dozen points of OBD-II data, the Derringer calculates Banks exclusive parameters adding even more refinement to its added power and safety. The system even compensates for altitude. Maximum safe power for the L5P powertrain is all automatic with a Derringer; simply select the power level and enjoy performance that you can really feel and trust.

Duramax owners can choose from two Derringer systems: Derringer with iDash DataMonster or Derringer with iDash SuperGauge. Both allow you to select from six power levels through the iDash and monitor up to 300 critical engine and tuner parameters, many patented, as well as clear trouble codes, check emissions readiness and initiate a DPF regen. The iDash DataMonster allows for simultaneous recording of up to 100 parameters on the included microSD card. The ultra-compact instrument can mount in an A-pillar, on the windshield, or in any 2-1/16” (52mm) standard gauge hole and displays 5 custom pages of up to 8 parameters each on its color LCD.
