okay so the trans is still mated so your flexplate and rear cover are still on the engine.
wet compression would be just squirting a couple shots of engine oil into the cylinders to keep the walls lubricated while the engine is spinning. this will allow for slightly better compression readings due to the rings ability to seal with the added oil.
I would pull all of the glowplugs so you get true unbiased readings on each individual cylinder. make sure the intake manifold opening is unrestricted too
BTW when you remove the ficm harness connectors from the injectors you do not have to remove the metal clips, they will press straight downwards and release without being physically removed from the connector.
