I was thinking about ordering a leigh performance 63mm bored throttle body for my 2000 XJ 4.0L. I have a cold air intake and dynomax exhaust. Would I notice better throttle response? Anyone have experience with this throttle body? Does it whistle? My friend has a BBK 62mm throttle body on his 4.0L Grand and it has an annoying whistle at certain RPMs.
