Your IAM is 0.56.  If it is below 1.0 your car is F'd.  You sir have far bigger problems.  When your tune calls for 10 degrees of advanced timing, you get 5.6 degrees.  The car will not make proper boost, timing or fueling as it is in LIMP mode. 

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).

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?

Cheers
