Message: What would be a better throttle body upgrade, going with the 46mm Fastman TB, or the 48mm V-8 TB conversion (can't go with the flometrics billet TB, costs too much)?

Message: I was wondering the same thing. I personally can't from checking out the prices why the 46mm is more expensive than the 48mm. Doesn't make too much sense to me, but what do i know.
