Just finished a full egr delete on the truck and now I'm getting the wrench with 5 codes; P0405, P0488, P041D, P1335, and U3F04. All have to do with the egr minus the last which is unknown. Just getting back from downrange and dont remember everything I read up on before. Would it be worth while to just retune via the H&S and see if that makes it go away? Kinda lost right now and need and extra hand. Thanks.
