NA engine goes richer too. Yes on LPG (unless you run liquid injection), you should never enrich past 0.9.
Higher EGT.

Thanks prj! Is there a rough guidance how much the timing can be advanced? Or can this only be done properly on a dyno?

On low load areas only on dyno.
Depending on the boost you run it is possible that on higher load also you will not have any knock limit and finding the correct timing will only be possible on the dyno.

I recall having to add a lot at low RPM and not having to add almost anything at high RPM, but this doesn't really help much - need to cell-by-cell dyno tune it.
