I think you do not have issue with specific cylinder, it is just more affected.
If it is injector, you would really feel the problem and had fault.
Usually two inner cylinders are most affected. I am not sure why, but they usually have slightly more missfires.

I'm getting timing pull when the misfires occurs in the correlating cylinders, I'm now thinking it's the tune, but it could be because I have added the bg44k so will wait for this tank to be used then do some more logging, because I have done logging before and there was minimum timing pull, at very brief moments for like less than a second maybe -1.8 intermittently which is brilliant for stage 3 car,  but makes sense that adding bg44k will have an effect.

Just an update incase anyone is interested, after running bg44k through the tank, and adding a little bit more octane booster I have pretty much removed any timing retardation on the logs, still get a few misfires on cylinder 2 though but a lot less, in an hour drive before I had 20 misfires on cylinder 2, now on a 5 hour drive I only had 6,
