Cobb Pro-tune help

Hey guys, I posted this on the other forum too. I dropped my car off at Cobb Plano last week to have my RBs installed and get a Pro Tune, and picked it up on Saturday. I didn't get to drive it much on Saturday, and it's been raining since then, so I still haven't driven it hard or done any logging of my own.

I was looking at the logs they provided though, and the timing and boost (in the logs) look a bit odd to me, can you guys take a look and let me know your thoughts? The car feels fine in daily driver mode, and felt great the few times I got on it a little on the way home.

Aside from the new RBs, N20 MAP Sensor, and CPE catted DPs, everything else remains as it was: Helix FMIC, Stett CP with Forge DVs, DCI, and stock Catback. I'm at 100k miles, so I swapped out the Coilpacks and VANOS solenoids, and threw in some NGKs gapped to .022 before taking it in to them.

The tune is 93 octane, no meth, and it was probably mid to high 90's out when they tuned it. I'm going back Thursday for the race map, but want to understand this log before I go back. They completely failed to do a map 0 run before removing my stock turbos, but I'm getting a map 0 run with the RBs when I go back.

The only other thing I'm a bit uneasy about is that I do have a siren noise (whoooOOOOOoooooo type deal) during low rpm, low load, operation. After reading on that for a few hours last night, I'm completely unsure as to whether it's an issue or not...seems to be plenty of dissenting opinions on the matter.
