ilde issuse's with big cam i6

i was thinking about getting a custom grind done for our au2 falc .is there anyway other than getting a chiptorque chip to get it to idle? i don't realy want to go through the dramas of pulling the unichip out and getting a chiptorque .
i remember reading on a forum somewhere that some had suggested to drill a small hole in the butterfly of the throttle body to help keep the idle up .do you reckon this would work or not?
thanks jake
