Default Anything weird in this log?

I seem to have some weird hesitation/missfire until the car is completely warmed up.
It only happens under very light load when cruising at a lower rpm and not in boost. Once the car is warmed up everything seems ok.
I'm running the OTS stage 2 Flash tune which is why I'm posting here.

From what I can tell, everything seems ok in this log.

I'm going to check the gap on the plugs in case it's opened up, but they were at 0.026" and are NGK iridium IX stock heat range.

Just wanted to see if I'm missing anything in this log.

The trims are a little positive but the LTFTs are not out of spec. Everything else looks fine. Is the hesitation at part throttle only or also WOT? Any codes?

Thanks for taking a look. It's at part throttle only. It's also only at a very small amount of throttle. If I give it a little more then it goes away. It's getting dark and rainy so I'll have to wait till tomorrow to check the plugs. Not getting any codes coming up.

Some surging could be BPV related. Make sure it is well lubricated and as always doing a leak check on both the intake and exhaust sides is a good idea.
