Any additional tuning required when installing a ported throttle body?

Title pretty well says it. I have a heads, cam, intake, injectors, longtubes, Blackwing, GHL catback, screenless MAF, Yank SS3200, etc., C5, with a full dyno tune. I just picked up a Shaner ported and polished throttle body. Do I need any additional tuning, or should I be all right just mounting it and driving with it. Thanks for any input.

You should be alright, it should be able to adjust by sensing more air being sucked through the maf

I was just wondering if the A/F ratio and idle could be affected and if tuning would optimize the mod.

Yes it will be effected, but the car will eventually learn the new settings.

Yes tuning would optimize the mod. If you drilled the stock throttle body and not the ported one it will be affected also. It will be able to pull more air and with ure list of mods it prob wouldnt hurt to get it on a dyno right after u do it to double check.
