Do an SD tune, if you have a Wideband it will make it a whole lot easier, get your VE spot on, then work out the MAF error. I think I have problems with my MAF also, have de-screened it, but not re-calibrated it. I dont think its a good idea to add a certain figure across the entier range, think multiplying it by a number would be better. But really you need to find the AFR Error when you plug the MAf back in and then dial in the changes to the MAF table.

You just sent the PCM into dizzy mode. The MAF isn't sending the same values per actual airflow as before. Therefore you need to recalibrate it.
