    2020 Chevrolet Silverado 1500 LT Trail Boss 5.3L L84 No Lean/fuelsaving option

    Sent out the ecm and got it back. Everything seems to be going good once I read vehicle and go to the engine-fuel- I noticed there is no tab for lean/fuelsaver like I had read there was suppose to. DOD/AFM delete was performed and need to turn off but currently stuck since that tab is not there. Any help would be very appreciated=.
