I appreciate that this is a done to death subject, but i'm on a slightly different track here.
I have turned the diaphragm quarter of a turn, star wheel down one turn.
What my issue is, is that the boost comes in very gently. I drove a friend's discovery, and the off boost/on boost transition is very snappy. His truck goes much better than mine.
I get reasonably dense smoke off boost and a light haze on boost to full throttle.
Any ideas? I wonder weather I should screw the low speed fuelling screw out a little to cut down the smoke off boost. I dont know if that would affect how the turbo spools up or not. Over all, what i have at the moment is an engine that feels, well, lazy.
