I took a look at fergals car last week.
the timing was a 2 degrees, when i tried to advance it i could only get it to 12 max CAS adjustment.
First impression was the timing belt was a tooth out after the belt change.
But his BIPES timing controller did not seem to be functioning properly either, it was showing a lot of timing retard at tick over (10 degrees +), should only be doing this under heavy load.
Fergal you should do as i suggested and disconnect the BIPES CAS wire at the ECU and remake the original connection, then check the timing. If the timing has not advanced check the pulleys.
On my car (and in the rod grainger manual) the intake pulley does not line up to vertical it sits slightly off tho the left when the cams are released, If the mechanic lined it up exactly vertical or slightly to the right it could easily be off a tooth.
When i brought the timing from 2-12 it gave better intake timing but your exhaust cam may be way out. I'm not sure if you took any notice of your boost gauge readings at tick over, if the vacuum reading is significantly lower it would suggest the exhaust cam.
If the pulleys are correct and the bipes is working then you need to test the CAS.
