Recently got my car tuned and I've been getting knock on the top of 3rd and 4th. I posted some pics of the tables from the tune. Does it seem off or super aggressive?
Ill post logs this weekend after I get the coolant leak issue resolved.

I can't recall where the BBK full comes in size and pump fuel power. How much of the boost?
Somewhat taboo to post a tuners map . That timing map is in the ball park at the higher load levels.Less is more in the end. Its always a good idea to check what actual timing you are getting with a light though.
You could try to take some timing out below 5500 as a start. It’s easier to prevent knock from happening then try and stop it once it starts.
A built engine can make more noise then a stock one, some times the knock filters need to be adjusted . Maybe one of the reasons the knock light is set to 8. Its a good idea to do that at low smoothing on a dyno to see exactly good/bad the engine is running when adjusting the filters. This will let you figure out real knock vs phantom knock. Running it on a dyno vs VD will also allow you to know exactly what it makes per degree of timing.
An hour on the dyno is money well spent IMO. Controlled environment and you can see what the engine is doing.
I removed the maps as I didn't know it was frowned upon. Once I have the logs on Sunday I'll post them. Other than the knock the car runs smooth and very surprised on how SD drives at low speeds.
