What's going on here?

This is a portion of a log that looked interesting. I think it's when I was slowing down to stop at traffic lights so I'm confused as to why the load increases towards the end (the continuation of this log is just a section of idling where the RPM and load values remain pretty constant)

As you can see, my load readings are still a bit erratic, despite me moving the take-off to a different place (tapped into the balance tube between the two intakes). I have silicone vacuum hose with a fuel filter and a mig tip in it

To answer my own question, think that was engine braking which makes sense. Since then, I've moved the coilpack further away from the sensor which has made things a lot smoother. After getting the HT leads back in right order (idiot!) the engine runs like a dream
