lukin4 inline pressure gauge to test /set actuator
Discussion
Dave,
best way to do it is via (accurate boost gauge) or even better via Freescan ! The MAP-reading is Boost + Atmospheric pressure.
This means that your 4-Cylinder should read at WOT around MAP 1.65 bar (~ boost 0.65 bar) if your wastegate actuator rod is correctly adjusted.
For doing this check, just remove the electrical connector from the boost solenoid valve and go for a test run.

Marcus, your test is based on a working capsule to adjust the rod. Dave is trying to a manual test as outlined in the service book to test the atual capsule itself. We suspect the capsule internals to be faulty. He has only been able to get boost above .5 with the rod extremely shortened. It is unclear why this is so. Only that this occured after service at a garage. No straight answers available as to what the shop has acutally done.

well explained calvin
going to try and get my stock 0.65 bar with the solenoid disconected tonight. if not i may be purchasing a capsule off you marcus!
im only worried that im just compensating for a worn/broken spring by shortening the rod as much as possible.
could this be the case?

Ahhhh ... I see !
To test teh acpsule I usually use a simple hand-pressure-pump with an integrated gauge. Quite nice to use. Pump to 0.65 bar and look if the rod just begins to move a tiny little bit. If it does not move (even at higher perssure, lets say 0.9-1.0 bar) then the diaphragma is shot and/or the capsule/wastegate is seized. If it moves far too early you may have a broken/weak spring.
Good luck.

I believe this is the one that will do pressure or vac....anyway, bluepoint makes what you're lookin for
