In my research on this site, I think I need a hole drilled in the throttle body. I get a nice idle at about 950rpm, with the ETC @ 11%. There is a slight hesitation when the throttle is cracked, I assume it is due to the ETC position being greater than 9%. If that is the case what size hole will need to be drilled?
Car is a 2006 Auto C6 with Cam, full exhuast, ProCharger, and 3600rpm converter. I have posted a log of the of the car idling if needed, as well as the tune file.
