Re: Throttle Bodies
For us 3.8/3.9 guys, it's really not worth getting a new throttle body until we start pushing some serious air into the intake. It's one of those mods that you hear mixed reviews about whent talking about power gains. Some say you don't really gain anything, others say they can feel the increased power.
I'm not sure on the 4.0's. They are more sensitive to changes like that and you might see some gains from one. I know most decent, worthwhile CAI's require a tune, so maybe you'd want to do the same with a new t/b.
