In the log you can see that

In the log you can see that you get a Timing Error at each 'hiccup'.  Timing Error could be the result of a missed cam tooth or an extra crank tooth.  I would take a log of the Advanced Pickups tab to grab crank & cam data so we can see what's going on.  

On a separate note, I personally would be a little concerned running 30+ psi of boost with O2 FB at +10-15% and AFRs still not quite on target and still slightly too lean.  If I was tuning this engine I'd adjust the fueling to get the O2 FB to be slightly negative and dial in a bit more O2 FB I gain - but that's just me.

You're going to have to drive

You're going to have to drive in the same way that actually makes the problem happen and not just take an easy cruise around the block, short shifting with low throttle and low boost.  I can't help you figure out the problem without a log that shows the problem actually occuring.

No dice my friend. No Timing

No dice my friend. No Timing Errors in that log either.  Did you turn the boost down?  This might actually be a true ignition misfire that results in a Timing Error and not the other way around.  What spark plugs are you running and what plug gap?
