This is exactly correct. A larger throttle body, giving that the stock one was indeed to small, will create less boost on a centri, and more boost on a PD blower. Less restriction after blower = more power and less boost. Less restriction before blower = more boost which is more power.
Meth before blower will give you a little less IAT cooling but it will cool the blower making it more efficient. Some say it "fills the voids" between the rotors and case, not sure if that is true or not, but either way, centri or PD, every setup I've had or seen has picked up 1-2 psi from spraying pre blower
