I'm with ron on this one, If you have checked the electrical side of things
which
you say you have, then i would have a hard look at the exhaust side of
things
as your pressure drop appears to be fairly linear, i would say the turbo is
maxed out
boost wise the whole time which means it either dragging, soot build up in
the exhaust
turbine could drag the turbine enough to not allow it to fully "spool" up,
or you have
a restriction in a pipe somewhere. If you had the turbo off/apart or had to
"FLEX" something
to get it back on after the service, then you may be distorting the housing
enough to slow the
turbo down.
well thats my 2 cents worth for what it's worth
good luck

Hi Paul
As far as limited boost on your 914 goes, first determine if the TCU is
opening the wastegate or if you have a physical problem. Cycle the
wastegate shut and turn off TCU and do a test to see if you can get max
boost, if you can let us know and we can go from there and troubleshoot
TCU. If it will not boost, it is a physical problem. Leak somewhere
between output of turbo and cylinders, (restricted intake????), or turbo
that is not spinning up fast enough due to binding, or problem with
impeller, make sure your wastegate is sealing AND CLOSING PROPERLY AND
FULLY, or could be a restricted exhaust.
