Fast VS BBK Throttle Body

I'm getting a BBK intake manifold for my 99 Corvette Hardtop, but i'm wondering which throttle body i should get. Fast 90mm T.B. or BBK 80mm T.B. BBK is cheaper but Fast is bigger. What do you guys think I should get?

Just an intake upgrade. Exhaust system and header upgrades will come next year.

with no other mods, I would think there is such thing as 'too big' in this case.

I like the BBK, ive had no issues with their products. As for sizing, i would go 10mm over stock and that should be boarder line for the mods you have.

Ive heard rumors about slowing the velocity with a TB thats too large, but i cant say for certain that happens.
