The knock during WOT pull could be a sign your fuel isnt high enough octane. You can always try a 91 map.

It would also help if you posted your exact car specs (beyond 2014 335i), mods, fuel, etc.
Thanks! I updated the post to contain more info on the car. Unfortunately the pull knock was on stock tune (I'm guessing by default that's for 91 based on the fuel requirements) but I might give Bootmod3 91 map a try
