As the other New Zealand 914 user that Bill refers to I add a little advice that
may help.
You state you are only seeing 34 ins, that is what you get when the TCU is not
working. How do I know, I took off the other day with the TCU switched off and
noted that I only pulled about 33 in manifold but was still getting full rpm,
5780 in my case.
This makes sense and though I do not suggest taking off with the TCU switched
off
it can be tried and would be a good pointer to see if your TCU is working.
That is apart from the usual checks to see if the servo is cycling.
Cheers Peter
