I'm still running the stock tune but I've been seeing some KR (0,4 - 3?) at WOT pulls past 4000 rpms (115 bar of fuel pressure, 1 bar of boost, AFR's below 11).

Went on holiday to Germany and as they don't have Q8 stations over there (have Q8-tankcard) I filled her up with Shell V-power racing (100 ron). I still got the knock countdowns (6? to 0? in ten secs) when cruising on the highway which I assume are just ECU callibrations, but I didn't have the WOT knock anymore which led me to conclude that while running the Q8 98 ron fuel my engine was more prone to knock.

I've read up on the HFS system some more and the HFS-2 setup might be better for me as I can still upgrade when I decide to up the boost later.

Has your car been modified?
