98RON + octane booster. Dyno runs on V6. Runs felt great. its super snappy and lots of fun to drive. 555hp at the crank and 750nm. 1step colder plugs gapped at 0.020"

RPM juggling on cruise control and normal cruising on the highway. Had it on V4 as i didnt have much octane booster with me in this log. but i also had the same issues on V6 with much more octane booster.
