This is very interesting how you all have the same tune and believe that the low rpm timing is way too high/advance.

Have you all discussed this with Alex and get a better understanding what this is happening?

I'll go back to stock tune tomorrow and reassess my option. I have been hearing the same thing and I thought it's just exhaust or engine noise as the car makes all sort of metallic noise during cold start (for my car anyway).
