Let me rephrase.

If you are stock, tune will make good power. Probably as much as 15+ whp.

If you have full boltons, tune will make no power. 5whp or less.

When you say car running rich OEM, how rich are we talking here?

I've seen stock Gs dyno'd and their AF ranged in the high 12s @ WOT.. I don't think that's rich at all. Adding all the bolt ons ie increasing air flow => leaning out, is when you start hitting 14s AF and thats when you need the tune in order to bring the AF to the VQs optimum 12s
