Put in some cooler spark plugs (NGK TR55) but still seeing 3.8* of KR at WOT.

False knock?

Dbextreme: Haven't deleted the P0140 code yet, and I plan on getting the car tuned, and I still haven't checked to see if the downpipe is hitting the sway bar (I don't think it is, but ill check nevertheless).

At some point I'm going to jerry a heat shield out of something to make my cone pull less hot air and see if that helps with overall power, but the KR I'm seeing is independent of intake air temps.

Which brings me back to false knock?
