Help please, Boost Problems - Mines ECU only going to 0.6 on gauge

So what's that; about 4800rpm?
For reference (standard ECU and ~1.0bar): at 6000rpm my AFR is more like 10.8, but at 4800rpm it's more like 11.3
If running 1.2 bar get it checked JUST IN CASE. I'm seeing this more now that these cars under fuel when boost is 1.2. Just be on the safe side get it checked.
I ran 1.2 bar with Mines ECU after a fresh re-build, engine is now in bits again as it was running too lean. Sold the Mines and will now be paying Ed a visit once I rebuild engine again soon to get it mapped properly :)
