you dont really need a bigger throttle body until you get to the 3.0 pulley area, which is usually achieved with an intercooler and rockers/cam. even then its not going to net you that much power if any at all.
I agree... however, I had to change from my 3" FWI to a 4" .... since I am cammed and its choking, I am going to have start looking for a new MAF since im starting to Max it out now. Never had this issue, until i went cammed and put on the 3.3"
