Great news whyzee125
Would be good to get another head trialing this. More info and all that.
Let's see how things go. I'll be regapping in the morning and will try to keep here updated at least by Monday.

Just wrapping up my part in this thread (although I may return to it in time to come).
Everything was going well until I did several WOT pulls and got my first ever error code for a misfire in 11 years at around 6k.
Thought it was the .023 gapping but for full disclosure, after checking my logs I was over-fuelling at that point so I rejigged my fuel map and it disappeared. However, I didn't go up to .024 because it did concern me that it might have been a factor given that I've over-fuelled at various points on maps loads of times in the past without getting a misfire so my guess is that I am on the limit for the boost i'm running.
Upon further tweaking my map I've managed to get a higher mpg with a change to my timing map.
I feel it would muddy the waters now to say that changing the spark plug gap will have made a difference so leaving them at .023 for now.
Am acheiving a stable 25 psi with no issues and clean logs.

I fail to see how .001" change in spark plug gap would make any difference at all. I would think that other variables like ambient temps, intake air temps, and fuel quality would have a much larger (although pretty minor) affect on things. Just the way you use the feeler gauge to measure the gap would probably lead to a .001" +/- difference. One persons"just right" is another persons "to tight" or "to lose".

I recently migrated over to B58 coils. Vargas recommended .018 for me so that’s what I run
