Default 3rd gear pull log question

I flashed to stage 1 a few days ago and right off the bat WOW what a difference! after about 50 miles of normal driving and no WOT. I did a 3rd gear WOT pull. (log found just below)

1st WOT pull log
https://docs.google.com/spreadsheet/...hl=en_US#gid=0

I thought it looked good (not really a qualified opinion) but i did notice some "fine knock learn" between 3300 and 4200 rpm. Not sure if this should be a concern I asked on forums if this was a normal thing, and have yet to hear a response. I turn now to NASIOC any ideas here?

Also worth noting is that I made a few runs since then and they seem to show progressively increasing "fine knock learn" and that I'm moving farther and farther away from target boost (16.5psi)

Here are the subsequent logs in order all 3rd gear pulls with Cobb stage 1 map.

2nd WOT pull log
https://docs.google.com/spreadsheet/...poaXc&hl=en_US

3rd WOT pull log
https://docs.google.com/spreadsheet/...hl=en_US#gid=0

4th WOT pull log
https://docs.google.com/spreadsheet/...RCYkE&hl=en_US


Any help would be greatly appreciated

Are you running the 93 octane map?

You have some fairly consistent fine knock learning at high load, but it is only a single count and begins to learn back to zero. Sometimes you get this specific correction on these cars that doesn't respond to timing changes. I would try reflashing the 91 octane map (while still running 93 octane) and see if it improves. If not, I wouldn't worry about it.
