Weird shifting and knock

Hi guys I just put a new basemap from cobb, its the AMS stage one with low wastegate because here in Canada its too cold and I get overboost CEL sometimes. So the dilemma is i seem to get alot more knock with this map, i attached the log if anyone can take a look and tell me if theres something wrong?

Also another issue is that it seems to shift really erratically in auto mode but it might just take time for the ecu to relearn again

Anyways my mods list as follows

Stage 1 AMS LWG map
AMS intake and upper and lower intercooler pipes
Tomei exhaust

Heres the link

I wouldn't worry about it. I see you have 2 big knock but you were on low boost and low rpm.

The log looks pretty good. I would not worry about the knock sum as it is very very minor and could be due to many reasons. Let me know if you have any other questions.
