Subaru Stars High FKL on a 2007 WRX WOT

Hi,

I did datalog the other day, and am a little concerned by the FKL of -5.6 at gear change, and I had a load of feedback knock today while just cruising back from work (-7 to -9.5 at times) while in traffic. The engine hasn't seemingly run rough, and the AFR has been predictable & stable while driving, so I just want to know if this is something I should be concerned with? Datazap is linked below. The map is Cobb stage 1

Get a tank of Shell gas and see if it goes away.

Otherwise send a datalog to cobb and see what they say.

Last option is protune the car to get it running in the most ideal form possible.
