Honestly, it sounds like you do have an injector going bad. I've replaced so many injectors on my car and this is how they all started. Slight hesitation that would turn into a misfire. Hard to reproduce on stock boost, easy when tuned.

The best way to test it is to lug the car (go in 3rd at around 2000 rpm and floor it).

The last one I dealt with was a little different now that I have a single turbo, but my point was that injectors can go bad very quickly. I am extremely well versed in dealing with misfires on stock turbos, which was usually bad injectors. Happens when you have replaced 20 of them.
going to log agsin tomorrow and keep an eye out for misfires. Also the hesitation is only in the beging the rpms before then by mid range its gone and by top end its movingg.
