Hi all, i have heard about noticeable gains on KK's if they swap the TB from a 4.7 motor to the 3.7, but has anyone tried this with a KJ? I can't find much about it on here so I'm trying to see if anyone has seen any gains in power, MPG, or anything? for the like 50 bucks that it'll cost, I'm wondering if its worth it. Does anyone know?
