Active Fuel Management Disable Tune

We offer a single-item tune that disables the Active Fuel Management (otherwise known as DOD or AFM) within the ECM on 2007-2013 GM Trucks and SUVs and 2014 Tahoes and Yukons. This option requires the ECM from the vehicle to be shipped to us to be updated. Please contact us for our mail-in form to include with your ECM.
