Gday guys!
Quick Overboost related question.
Iv had my egr recently blocked and Dawes and needle valve installed. Boost is set to 18 psi. Everything seems to be running pretty good now apart from one slight Overboost issue. I usually sit around 105 km/h and the car runs fine but when iv got to get that little bit more out of the car, usually to overtake a road train or caravan the engine light comes on due to over boost. I try to get a bit of a run up and gradually increase speed before overtaking but it's not always that easy. It happened the other day just as I'd pulled out to overtake a road train (was not a pleasant experience), anyway I'm guessing it's due to the turbo spool up being to quick? To fix this is it just a matter of winding the needle valve in slightly?
Thanks guys, car is a 3ltr series 3 wagon manual.
