Even with a blower, there is zero need to touch the TB until you are at or beyond 500hp as BLOWN FORD has illustrated. The likelihood that the TB is the constraint will be low unless you are going for higher boost levels out of the box, in which case, you may be on borrowed time for the bottom end at those levels.
