Are people not getting the concept that the maf response is instantaneous and there is no Limbo time between when the air enters the maf and when the ecu adjusts?
You run rich AFTER you blow off. The system takes in more air for the air that was lost and you dump fuel. When you recirc you take in less air thru the maf and don't run rich.
