I've searched but found no definitive answers, so;

Can people post some maps for me to look at and get sn idea of a starting point pretty please!!

And What's the best timings to use on engine over run?

I think I remember someone saying the run upto 56 degree advance off boost to keep the turbo spooled?? Or am I imagining that?!

There is somewhere here a discussion with the will_h or Rob's ignition map, don't remember. I'm running 29 deg at 1bar on 998.
To keep turbo spooling: I think it all depends on your setup: turbo size, engine size. I was not able to improve response time although I played with lots of scenarios (richness, ignition). I can do anything as I'm writing my own ECU code. Quick shift works well (maintain RPM while shifting) but it's not really turbo related.
