.7 bar is about 10psi. I think you could be seeing 11s with your set up.

Here's a set of datalog charts from my car. Its a composite of 4 20 minute session on track at NJMP. The top chart shows average AFRs vs. RPM and MAP. I'm a bit leaner than your readings at 10psi, but then I have larger displacement and my intake ports are opened up 5mm so given the same indicated boost level, I should be flowing a bit more air than you.
