you don't want to mess up your nice TB you should just not get the cam. LOL

every car is different but learn from my mistake let the car do a little relurn before you drill or it will end up to high. also just a little at a time.

I read somewhere on here that it took like 7 trips out to get things relearned a little better.

i know our puters are picky as hell

I'd say one full day of driving and you'll notice the difference. But, there is really no guesswork involved here as long as you use Atap. Just make sure you have the car warmed up all the way, read the IAC counts at idle, and drill accordingly. You will see the results immeadiatly from the drilling.

IAC = Idle Air Controller.

HD: IMO, anywhere from 20 - 40 is fine count wise.
Don't forget you gain air by turning the TB set screw about 1 turn. This reduces the size whole you need and is a reversable adjustment if the IAC drops too low. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
