[1slow320i]

Flashed my 2015 bmw 320i to bm3 stage 1 91 octane and logs looked fine except for a knock getting detected on the logs. It doesn’t sound rod knock and I doubt it’s the timing chain since it was replaced recently with less than 2000 miles on it. Spark plugs are at original gap. Would really appreciate any recommendations and thoughts on what it could be. Please let me know if any other logs are needed. THANK YOU

Mods:

The log I attached wasn’t the greatest here’s better one.

That's useless
Do a log from 2500rpm to redline in 3rd gear.. 100% full throttle.
