Did 600km in two trips in the last 24 hours. Plugged the AP in about halfway thru the 2nd trip and kept a lazy eye on a few engine readings including knock retard. Highest ive ever seen it. Up to 4.3 at one point. Ambient temp 35+ most the drive. Aircon on. Stock 07 mps 3 66XXX, last oil+filter 6000km ago, checked and topped up last week. Cobb AP V3 w/stage 1 98 tune.
See short log attached. 3rd gear WOT, knock pings to 3.15.... help?
