Yes. I wasn't sure initially if he appreciated it, but he warmed to it when he realized that I was pulling his leg. He drives nice and clean and was getting the apexes sorted out.

This is me chasing down a Boxster S, somewhere past the 5 minute mark. I passed him, but not until after my GoPro filled up....just before the point-by so you can see my closing up to his bumper. The guy was definitely pushing hard trying to stay ahead of me! The track was mostly dry by then. I had a great time and there were only 6 or 7 cars out. No traffic to speak of, so I made sure I timed getting on the track for when those guys went out because it's a lot more fun that way. There were three Porsche GT3s there, too, but (and I hope they don't read this!) they weren't expertly driven so they were easy to haul in. But....they were doing exactly the right thing by taking their cars to the track and using their cars for their intended use. Once they learn their cars they'll wax my butt for sure!
Boost went way back to ~5 psi a couple of times on Saturday. After I toggled the ignition, it always came back. Searching the VW/Audi forums I'm confident that it's the famed N75 valve -->
