Nah blank didn't stop the ticking, good to see yours is sorted mate, mine had new battery and cam sensor year and half ago and I recoded injectors Sunday night. After a few days with my boost gauge fitted it still shoots up to 2bar (max on my gauge) and holds there, then when it runs ok peaks at 1.5 and drops to 1.2. Sucked on the pipe to actuator and it holds steady, but when the engine had a few revs on its in and out like a bloke on a prozzy, am sure it should be holding steady.
