Peter,
I eventually get 38" at 115% throttle setting. I get 34" at 100% throttle on the
climb and it maintains 34" to 12,000 ft so I assume the TCU must be working.
The TCU cycles perfectly on turn on.
Having said that, I can certainly try a T/O with the TCU turned off to observe
what happens.
I need to have a fly behind another 914 in case my problem is only imaginary.
Thank you for your help.

rpm,
5780 in my case.

That is apart from the usual checks to see if the servo is cycling.
