Edge CS2, CTS2 tuners now available for 2016 GM 6.6-liter LML Duramax

evolution-cts2Edge Products announced that its Evolution CS2 and CTS2 tuners are now available for 2016 Chevy and GMC pickups equipped with a 6.6-liter LML Duramax engine.

Edge has also re-engineered and released all-new, 50-state legal calibrations for the 2011-2015 LML Duramax.

“Gain up to 135 horsepower and 240 lb.-ft. of torque with the performance tune,” an Edge representative said. “Use the tow tune to haul those loads, and watch mileage increase with our innovative tuning.”

Edge reports that extensive testing with the CS2 and CTS2 tuners revealed greater distance between regen cycles, greater power and throttle response, and improved mileage over stock, all while in tow mode.
