No tune 8 hp
Tune 18 hp just airflow tuning
Supertune 65 hp with a full tune and intake

depends highly on who does the tuning but I can't see it changing the VE of the engine that much with just an intake. Of course, If they redo timing and tq man and fueling they will get a lot more than if they just tune airflow.
