It was time to have the oil changed (2300 mi in my TB Daytona so I took it to the dealer (first one is free). When I got it back, it was like a different car, barley touch the gas and she lights up the rear tires. I had been running SC 91 tuning before, but before my trip I flashed it back to stock before my trip just in case they did a flash at the dealer. After a few miles, she went back to her old self. Any ideas what they did?

It would be very interesting to know what transpired, flash, PCM reset or other adjustments.

If you didn't get a maintenance record printout after your visit you might want to call then and have them print you out a copy. Keep these in a file for your reference and some people like to see this file if you ever resell the car.

PM me the last 8 of your VIN, I can see if they did a flash.
If they did, they would have submitted a claim to get paid for it - and I should be able to see it.
