Anyone on here know their way around an RS TUNER?

Done some logs, what I've noticed is there is an increased number of knock counts not on WOT but it's concerning,

I've changed exhaust and it'll be getting mapped to suit but I'd like it if I could send a couple of logs to someone who's in the know so they can have a quick glance?

Also the rev limiter has dropped slightly

Mucho gracious
