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
