Well in the case of the Barra182, thats using its VCT for fuel economy rather than power, the XR6T has a different program to use with the 6psi boost as does the F6 which has each cam working independantly with the 9psi. So if Ford were to factory supercharge the engine further down the track, the VCT would further help them with that as well. Its alot of small gains found all over the place that adds up in the end
