Ok guys, so I noticed that once I go WOT and revs pass 7000 RPM my NA oil pressure gauge goes funky. It would flicker and drop to around 2 bar of oil pressure.

I found a thread at M.net indicating that the NA oil pressure sensor would act as a knock detector. However, I tuned the engine using homemade set cans and cannot hear any knock (13-14 degrees of timing at 230 kpa, running RON 100 fuel). Is it possible that the sensor picks up general engine noise? I don't think my oil pressure actually drops, and I can't hear any knock. But then again the car is loud as hell anyway once i get near redline.

Has anyone else encountered a similar problem? Attached is a video doing a 4th gear pull until I hit the rev limiter

You should add a proper standalone OP gauge, the factory gauge is known to be inaccurate.

Pull 2 degrees and check again? Pretty simple solution.

Can't drive the car right now due to winter, but that was my first idea. Until then this uncertainty is killing me.
