i’m running mhd v7.1 stage 1 map,arm charge pipe with a tial 50mm bov (11 lbs spring ) fresh index 12s and
my rail pressure seems to be okay, new plugs and high performance coils , car runs and drives great but whenever i flash anything other than stock maps i get crazy high afr values but the car still performs well and doesn’t miss fire or anything. any ideas why ?
( i’m new to the bmw world so i might just be trippin) also if there’s anything else in the log that doesn’t look great lmk, still learning how to read them.
