Re: Throttle Body. How big is everybody going? mm?
If your gonna do it just from personal experience, get fastman to port it all the way thru whatever size your gonna get. Had a 85mm on my 08 that was just ported at the ends and there was very minimal difference, sold that and bought one that the butterfly was swapped out and ported 85mm all the way thru and it really opened up the top end and throttle response. Have heard it can cause idle issues on some Jeeps though but mine never had any issues
