Pretty rare to see MAF displayed in lbs/minute.
If you have the ability to monitor for and graph misfire data, I would look there to see what cylinder(s) may not be contributing during your hesitation. If you are seeing a pattern for 1 or more cylinders, focus your efforts at determining what is causing the issue. As far as your IAT and ECT, they appear to be ok but all should be checked under the same conditions as your hesitation. Duplicate the situation and problem first. Monitor your scan data during the event and record it. Most times your problem will show up in the recorded data.
Also curious as to the vacuum reading. 29.92 in of vacuum is what is referred to as "Max Achievable Vacuum" and isn't something we see in automotive vacuum readings. Typically you are looking for 15-22 inches with the needle or reading holding steady on a properly running engine.
