Brother I swapped the calibrated 30 lb maf to the new pro m and it won’t run right
Are you saying that you took the sensor itself out of one housing and put it into a Pro M housing?
Or are you saying that you put the entire MAF housing (the one you have been using and has worked well) and attached it to a different cold air kit?
Once you remove the sensor from the housing it was in, you've completely changed the transfer function of that sensor. (in other words: No juju)
