Tested range AFM disable on my 2014 2ss rs vert.(cai BORLA Axel back exhaust) 200 mile round trip. 25 to 60 mph speed limit with a average speed of 57 mph. On trip to ave 23 mpg with range on way back 26 mpg without. AFM noise OK without range at highway speeds but very irritating at the 25-40 mph. So to me giving up 3 mpg is will worth keeping in 8 at all times and no codes either and the BORLA sound is great (s-type).
