Not revving past circa 4.5k revs is usually a sign of failed/failing speedo sensor, isn't it? (It's some kind of Subaru failsafe mode).

Does your speedo work correctly?

**** it into Xtreme Scoobies in Boreham - the guys will no doubt suss it in a thrice...... Or maybe even a trice!

I'm stumped.

As it's seemingly not a w/g or BCS issue, if it's boosting to that figure (albeit not the full target boost).
