So, I know a 73mm throttle body is alot of overkill for a stockish jeep 4.0, but will it cause power loss instead of giving me more power or will it just move the powerband to a less then optimal rpm range?

It will cause your throttle to be more touchy. Don't do it unless you really need it.

Or do it and tell us how it worked out... I have a 60 (63mm... 60 something...) mm throttle and it def helped out my low-end
