Had another look at it today - hooked up the 'turbo pressure vsv' that wasn't connected, although it didn't seem to change anything. Whats it susposed to do?? Have a more detailed description of what it does -- When the revs reach 1300, there is a sound like a tiny BOV, the air flow meter opens more to indicate there is more air going into the engine. And then the revs drop to 900. They then climb back upto 1300 and repeat. Have checked both AFM and TPS - all are working fine within set ranges. As far as I can tell there are no boost leaks, and the wastegate actuator doesn't move. [Report message to a moderator]
