Drilling throttle body?

[Saltmaker]

Can anyone tell me what size hole to drill in my throttle body? I was told this will help the car idle a little leaner and better... But I'm not sure what size to drill does anyone have any experience with this? Thanks!!

Hum..i have never heard of this...and it sounds kind of wierd. if you drill a hole in the throttle body, wont you be letting unmetered air in? unless you are talking about drilling a hole in the butterfly valve itself? if someone could explain how this is supposed to work and help that would be cool. just trying to learn some stuff thanks

you drill the hole in the butterfly....this lets air in or whatver it does, but it cure idle problems with cams alot of times

As a side note: I installed my 76mm MAF yesterday and I looked at my throttle body and it looks like the previous owner drilled the butterfly on it, I've had it since '98 and didn't even know it was done.
