Default Another question on cam install.
How big of a hole needs to be drilled in the throttle body? Cam is a TR224 112 on an M6.

Drilling the hole larger in the throttle body blade is not a substitute for getting programming. With a TR224, I would highly recommend getting programming to help with low RPM problems. Then if you want to smoothen out your idle a little bit, you attempt to drill the hole larger. There is no standardized hole size that you need to go with for any cam. To me, its just a band-aid.
