I have seen posts about dyno tune events... and wondered how the "tune" part of it works. Does the shop use flash programming to fine tune the ECU settings..or reprogram the chip we might already have? do they tweak shift points, fuel mixtures, etc..?? what do they fine tune?

or reprogram the chip we might already have? Yes
do they tweak shift points, fuel mixtures, etc..??? Yes

They also monitor A/F ratio...and they do all this while running the car on a chassis dynamometer to check whether the tweaks are performing properly, (or they've gone too far) and measure the actual power being delivered to the rear wheels...
