I have zero skin in this, but have you personally flowed these AFR's on your flow bench? They had the flow sheets on these right in their booth at sema, with comparison numbers to eagle, apache, and the early heads. These were up around 15-18 cfm as cast, peak, vs apache if I recall. So I'm just curious as to what basis you know their claims are false. 18 cfm is a mathematical increase last time I checked.
