i have just a few bolt ons... would a throttle body give me any kind of noticeable difference at all? and should i get a 65.70.75mm?? any inputs? thanks

unless you've changed the cam or heads, you don't really get that much extra from changing the throttle body. since stock is 59 mm, going up to 65 is a bigger difference that most people think. 70 and 75 are more for serious cam and head mods also.

Depending on what year you have if you do that you're also gonna want to upgrade the mass air, that is if you have one.
