Log looks fine except that you are underboosting quite a bit. Are you at altitude at all? I would give the high wastegate HWG map a try, which you can download from our map repository:
http://www.cobbtuning.com/info/?ID=3061

Some of your long-term fuel trims (A/F Learning 1) are borderline (around 7%). Generally, these should be +/- 5% and anything outside of +/- 8% is likely a problem, so you are kind of in-between. I would consider getting a pressure (or smoke) test done of the intake to check for leaks and continue to keep an eye on A/F Learning 1. Another thing with these cars is a MAF sensor that degrades over time and progressively reads lower and lower, but your reported airflow is reasonable, so if this is an issue, it may be borderline as well.

No, but you do not want to be running around with an exhaust leak (i.e. carbon monoxide poisoning).

There is a lot of variation from the factory for these cars as far as hitting the boost target is concerned. I would give the HWG map a try and see if that improves things.

Boost looks a little better, but you have some knock events during the WOT run. In your first log, the long-term fuel trims are still trending positive and some of them are borderline. I would do a pressure test of the intake to rule out any intake leaks. I would also switch to the ACN91 map for now until you get it figured out.
