What throttle body should I put on my 02 Mustang GT 2V?? Here are the two options: Either a BBK 75mm Throttle body...Or a 70mm throttle body? I intend to put a supercharger on my mustang and I wanted to know if the size of the throttle body matters....75mm belongs to the 02 Mustang GT, but in the other hand, they recommend a 70mm to the supercharged application..help...thanks

I'd got 75mm.

With boost, the bigger throttle plate is less of a restriction, and you don't need to worry about tipping in.

with a booster...you cant go wrong...get the 70 though, as your not boing to be making 20 psi of boost.

But with a 75mm instead of a 70mm, wouldn't it work slightly better with a supercharger? and...Even if I would get the same result with either size, bigger is always prefered more with throttle bodies, right?

The bigger throttle body will increase airflow but it'll reduce air velocity which may reduce hp. Bigger is better on the high-end and vice versa.
