Any ideas what can cause this, or how to go about fixing it?

Don't think so, I tracked that and it seems all good. https://imgur.com/a/tDlP5hj I added Spark timing to the tracking, here are the results: https://imgur.com/a/y2n7Ocs Looks like the spark fails before fuel is cut?

I'm having an issue with my '06 JDM. I've posted a bit more about it here if anyone fancies taking a look: 600 RPM drop. Picture for attention

Hi, Looking for opinions on what the cause of the issue I am having might be. No check engine light. Vehicle: 2006 Legacy Spec.B, JDM Automatic. 2.0L Basically, often when reaching higher RPMs the car will 'miss a beat'. It loses power for a fraction of a second, then continues to rise through the RPMs fine. This usually happens at higher speeds, e.g. when quickly going from 80KM/h (50mph) to 120 KM/h (75mph). Images of the issue: https://imgur.com/a/cP5aPgt I've had the car for about a year now, this problem only began in the last 2 months or so. I purchased a data logging device, I'll attach a csv file if that can assist anyone with diagnosing. I'm a complete novice when it comes to working on cars. As far as I know, my car is stock aside from having it tuned to 91. Looking at the data, fuel being sent to the engine all but stops for a moment - then quickly resumes?
