Not 100% on point, but close.
I was going to get a 62mm twin throttle body, but the salesman at Steeda talked me out of it. He said that unless I was running 12-14 lbs of boost, or a seriously modified intake and heads, that the 62 would be over kill. It may give a little on the top, but that would be more the canceled out by the loss of torque on the low end.
I'm sure the same applies for the FRPP single bore throttle. That and you have to grind a good amount off the intake to get it to fit.
