It's just a turbocharged Piper Seminole that a friend has to pick up! We are going from Vegas to Spruce Creek, FL with it this weekend. I couldn't pass that one up.

Expect a slight turbo lag when you go from idle to high power (but not as bad as a jet).
Let the turbo spin down and cool down at idle before you stop the engine
I read about the waste gate obviously, but the AFH didn't really mention the manual/automatic issue. Another book I have did mention it, but didn't go into any great detail. If it's manual, how do you know when to use it? And is it an on/off switch so that it's either on or off, or can you open it a little or open it a lot as required?
I also read a bit about the fact that the turbocharged engine runs at higher temps than non-turbocharged and that a richer mixture would be required. Is that what you have noticed, and how you have dealt with the higher temperature issue?
And as you mentioned about letting it cool down at idle before stopping the engine, I read that you have to more carefully plan your descent so that you do not damage the engine from cooling stress. Any tips on that?
