With our Coyote engines, you can very easily tune a lope by dialing in the TiVCT to close in the LSA and increase valve overlap.
The 2009 and earlier Mustangs did not have TiVCT so they relied on fixed LSAs of their cam profiles and possibly some exhaust mods that would provide some sort of back pressure or exhaust return pulse to cause the exhaust gases to seep in with the fresh fuel-air charge to contaminate it for the next combustion.
