It's not a question of high RPM performance. It's about taking advantage of the 24 valves a little earlier than Ford intended. The only way to improve high end with this system is to toally remove the secondaries. This tie wrap them open idea was thought up as a test (at least in my eyes) to see just how much we'd lose down low before tearing up the intake only to find out the low end loss was to much.
Sorry great ride. My secondaries were tied open at SZ01... With the SC is was no question it helped.
