Larger throttle body/intake opening effects?
Typically, what changes (besides the obvious VE) would I need to do to the tune when installing something like a FAST92 w/ throttle body. Since the area of the throttle body has changed, what else would need to be calibrated? MAF?

If you are switching from stock, you will need a full drivability tune to get it back to perfect and to figure out if the TB needs to be drilled. If you are going from a 90/90 to a 92/92, I bet you wont see much of a change at all unless the old TB is drilled and the new one isn't.

I'm the person who has inquired about the clutch install (Ryan from St. Aug.)

Why do you have to adjust the IAC Effective Area? Is the opening for the IAC valve larger in the bigger throttle bodies? I've seen an Excel Sheet that provides a multiplier for the Effective Area but don't see how it relates to the steps on the IAC. IAC is a throttle body bypass isn't it?
