I was thinking dirty o2? Any advice would be appreciated.

When at Idle - AFR's will bounce around from 13.9 -14.7 same with a cruising speed. Ideally it should be 14.7 at idle but our digital gauges and with engine pulses - it's practically impossible to stay at 14.7 all the time.
Even at WOT - we see our AFR's go to 10.5 - 11.5 or so... they never just stay in the 10's or 11's.
I used the AEM tru boost on another turbo'd vehicle - and same thing. It always jumps around a little.
best of luck
With Sasha... you are missing a "h" in his name... thought I should let you know..
