If you would like to remove DOD/AFM (displacement on demand, four cylinder mode) system from your ECM, please use this listing. Send in your ECM and we will disable it permanently in the software so that it will only run in V8 mode. Turnaround time is usually same or next day. We support almost every Gen 4 ECM 2015 & older (i.e. 07-13 FS Trucks incl. 2014 Tahoe/Suburban/Yukon, 10-15 L99 Camaro, 08-09 G8) . If you are not sure if we support your vehicle please ask first.
