2016 - 2022 2.8L Duramax VANS | HP Tuners

TWD tuning for Express and GMC Savana vans is designed to improve horsepower, torque, and mileage while providing multiple calibrations for different performance needs. Available tune levels include Tow 20HP, Eco Tow 30HP, Street 50HP, and Performance 60HP. Transmission tuning further refines drivability with earlier converter lockup, increased line pressure, revised shift strategy, earlier downshifts with less throttle input, and adjusted torque management.
