I'd lower it for both safety/ease of tuning, and peak power potential (bigger giggle-factor lol).. So much easier to turn everything up as high as it can go and never worry about detonation.. I am worried about how it will feel off boost/low compared to the n52 with it's 10.7.. I know i won't care in the end though lol
Raising it sounds nice for off boost and response, but it a much bigger headache for tuning... Number one goal being reliability, i think i'll stick to 10.2 or lower lol
I'll be wanting e85 an possibly a flex fuel sensor if the jb4 gets the ability to (unless i can afford a proefi an put it in one day haha), as that's likely what i'll use to start with simply for convenience

Vargas has td-03s shells with td-04 internals. So, if you got them laying around, don't mind having a look to see what sort of room I have if I want a special turbo built.
Safety is definitely better to be lower for peak power, and raising it is definitely much more dangerous and harder to tune. The require piece is a new gen spark plug that federal mogul has developed, but at the moment is only given to OEMs and can run 14:1 compression ratio. I tried to get it from them about six months ago for development and they said no to aftermarket for the time being
