11.0 or so is plenty rich.. I actually run 12.0 in most areas on my car since it isn't "Unhappy" with the timing I'm using and my EGT's are fine for the type of driving I do with that map. I also noticed that on Long Island, the gasoline has 10% ethanol in it, and has generally allowed me to run a pretty aggressive pump gas tune compared to other pump gas maps I've seen.

 

Doublecheck the torque on your studs periodically.. I found that (and so have others) the stock studs are fine through 26psi if you haven't had anything apart yet. If you upgrade just the studs, without a new head gasket and checking the sealing surfaces (deck and whatnot for square) the studs can walk themselves loose and you may lose a head gasket with high cylinder pressures. I have seen this on at least 2 occasions recently.
