Probably because you have 310's and a FMU. They usually go pig pig pig rich right around there. Usually people use an FMU with just stock injectors and they flood the motor half the time. Your 310's probably put the afr off the chart.
Matt
ps- If you have a "Chip ECU", get rid of your FMU and run uberdata.

To answer your question, i would run stock timing and 2 step colder plugs...
try using a recalibration kit if you still want to use the FMU. I remember i had 12:1 disk and stock h22 injectors and it bogged real bad when boost kicked in...a/f was done past 10:1...
you can either try the recalibration kit and drop the FMU disk to a 4, 6, or 8:1 with your 310 injectors. Or you can try leaning it out with say...a V-AFC...

Sure hope you're not using the E-manage with that fuel setup... either way it seems you're running way rich. Does your "chip" advance timing? That's a big no-no for boost.
