i've also seen an rs2k 4x4 at ava back to back with and without cone and the airbox was 8-10bhp more!
Chop, were these all done on the RR though, as that will always give a better reading than a cone if the car is standing still IMO, good if you want to get a good RR figure but what about when the car is actually moving?
