Remember the AeroPeru 757 that crashed into the ocean because the tape the
painted had put over the static ports had not been removed?

Ken,
This sounds a lot like the problem I had coming back from Oshkosh last year.
My problem was surging while in the air and the engine seemed to always work
on the ground. My problem was a plugged static pressure sender going to the
TCU control circuit. Problems like this can be caused by the airbox or
static pressure sensors or a leak in anyone of those little black hoses. I
pulled each off house during troubleshooting my problem and used a small
syringe to pressure them up in some soapy water to look for pin hole leaks.
My problem ended when I pulled the static pressure sensor and found the end
block with a rubber cap the painter had put on to keep out the dist and
overspray.
Just a thought for other places to look for your problem.

Yesterday taking off, the engine surged as the turbo kicked in it went up to
5700 RPM then dropped back into the 4800 range. I tried several runs but
aborted the take-off as it continues to surge. Checked the prop governor
and it checked out as functioning correctly.; Took the cowl off and the
turbo arm seems to cycle correctly when the master turned on and the
throttle cycled. Tied the plane down and ran it up to 5700 rpm. It did not
surge at all.
Any idea? I have not tried to fly it again yet.
