So just ordered my Stillen SC

I know safe is good but kind of looks to be quite rich.

also what sort of timing should we roughly be looking at? I can ask what it's at or any graphs of it, forgot to ask about it. Any help would be appreciative and I can point them in the right direction and we can do some testing to make sure there's no detonation.

It's currently middle of winter here, so out and about most places where I am, gets down to 0ish-10degrees celcius while nighttime, would you also advise a sort of summer tune? pull back some of the timing during the hotter weather?
