Im finding that after some tuning in closed loop light to mid throttle, the AFR fluctuates between 14.3 & 15.3. Can anyone confirm if this is normal for closed loop operation. Im thinking that If I switched open loop I can control AFR better. Please chime in!

In open loop cruise, mine does not fluctuate this much. I have read closed loop speed density doesn't like single turbo setups. Post up your tune.

Closed loop operates by switching rich to lean around stoich, so that is normal. There is a hidden parameter to control how much, but I haven't played with or proven it yet.
