58 mm throttlebody
Is one brand better then another? I see professional products is cheapest. Anyone used one of theirs?

Re: 58 mm throttlebody
Why do you need a TB that big? Gonna seriously compromise your tip-in performance off idle.

Re: 58 mm throttlebody
I've never had "bad tip in" with any of them.
I know the BBK 58 makes a loud air sucking and whistling noise, atleast the 2 I had did.
Other than that, they all work about the same. Just pick the one you like the looks of and have at it.
Or look at the mono blade T-bodys. Thats what I run.
