I have flown a Piper Seneca a few times with manual boost control via
cables. Works all right, the only thing is - you have to pay attention when
you descend that you don't blow off the cylinders.
One thing that I remember vaguely is that I wished for a venire control
instead of a simple push pull handle to set the manifold pressure better.
Since it takes a second or so for the pressure to respond to the waste gate
adjustment it would be nicer to gently turn the control instead of trying to
push it a fraction of an inch. This may be really helpful too when it is
turbulent.
