I Have 50 hours of operation on my LANCAIR IVP.

Here is my list of questions. The list becomes fatter every time I take the
kit flying.

1. Flying the pattern for touch and go; Should I worry about quick power
reductions from 38 inches on take off to 25 on crosswind to 20 and down to
13 on downwind all these setting changes in probably 2 minutes?

2. To maximixe range: If my cruising altitute will be 18,000 , should I
start leaning during climb as long as I watch temp limits?

3. Flying above 6,000 I have experienced loss of turbo power three times.
From 31mp to 23mp. Power is back in 6 seconds with a few seconds of surge. I
have noticed that high humidity have been a factor every time it happens, I
have been already leveled at my cruising altitute flying the engine FULL
RICH.

Can I suspect the problem can be cause by a mixture too rich?
