You'll be fine to have it on 'ADD' unless you go over 500hp (The MAF's readings through the Selin Translator are most accurate on ADD!). As soon as you set it to AVERAGE (going over 500hp), the ecu will need to be updated to double the MAF reading (and retune for 500hp!!), but you will also loose half the MAF's resolution in switching to Average as well.
