Here is my 'ghetto gauge'  Used to test boost on a Saab 9-3.

Approx 1 bar.

1 Bar? A Griffon took 82" with water meth on take-off.

.. and was a tad more spritely than a 2.2dti.

Intake temperature might be a clue as to its' better performance when cold. Check it's not drawing warm air in from the engine bay via a split duct. Another possibility is that the intercooler is not effective - clogged / fan failed (if fitted).

Have a decent intercooler here if required

Remember to keep it front side up, unlike the messy bastard who moved it last

I think 1 bar is a little low for the dti as when checked it's peaking at 18psi and settling at about 13psi at wot ...so I'm loosing about 5psi ..actuator weak ?
