Welp if that the way you go, toss that ZZP tune in the trash because it's worthless if you go the Northstar and different MAF route.
ZZP will never be able to send you anything worth a salt because they don't have a clue how much air the engine needs. It will need a complete retune of the MAF airflow table from scratch along with WOT tuning and so on. Just thought I'd say that because many don't know what really has to be done.
