still not posible one reason being the turbos share a common induction system , charge pipe, manifold ect. second reson being 6+6still equals 6. although both turbos are contributing equally , the system is equalized by the y in the charge pipe . if he said one turbo is moving 30lbs min and so is the other 30 lbs+ 30lbs would equal 60lbs min. he would then be correct.
