Hi all

Have recently posted a thread on here relating ot my a6 audi 2.0 tdi 2005. Engine is blb. Have changed various valves sensors etc relating to "limp mode" and various fault codes, before going down the route of a turbo change.
Performance has improved slightly, but still going in to limp mode when accelerating or going up hill. Mech checked boost pressure and its running at 1300 at 3000 revs. Is this normal or can anyone explain what the average boost should be please?
