You'd be better off asking that question on voc.

its not fuel cut is it? or is it chipped? the fuel cut is only like 0.9bar isnt it?

It probably IS fuel cut as it should happen at 1bar 14 to 15psi...

My 940 2litre turbo was set on 13psi and went great but just a bit more and fuel cut.

Keep it at 10. As it's been quite cold you'll just about hit it at 15.
