Not actually... A single 90mm throttlebody will flow more air than twin 60mm throttlbodies.

60mm TB: 60 x 60 x 3.14=11,304mm2 surface area
x 2 = 22,608mm2 surface area

90mm TBL 90 x 90 x 3.14=25,434mm2 surface area

So yep, Id rather a 90mm anyday :) Not to mention multple throttle's mean multiple throttle plates which further reduce the area.
