If you've tuned the VE table, then most likely your MAF calibration is off. That code is normally because its exceeding the P0101 table where it shows how much it can be off before it throws the code.

If your VE table is on point, then use some of the MAF calibration spreadsheets in this forum and re-calibrate your MAF. It will get rid of that code and your LTFTs will be inline with the MAF running.
