Positive fuel trims disparity
I have a 2013 m5 that is having positive fuel trims on bank 1 around 15 percent ltft. I have swapped 02 sensor sides, maf sides, reset adaptations and no change. Occasional code for lean on bank 1. Smoke tested it and no leaks. Fuel trim comes back down to normalize when on throttle. Only mods are turner exhaust and air filter with charcoal delete. Maf flows attached and appear to be lower on 1 bank. Are these flows normal at idle?
