The 2500 was the plate they gave me. Go figureThanks everyone
Did you get the 2500 license plate already
Afraid not dude, 6th gear too expensive unless we get like 20 orders

Destiny awaits you
This is the table of trims that PCV Autotune is recommending me after the first couple of rides.
As you can see, I'm taking it very easy as I'm not sure about running the engine in so am being precautious, only used 7-8% throttle and up to under 3000rpm so far.
But the thing is looking for a lot moar fuels, which I am delighted with.
Interesting to see that it's not looking for just 8% more (8% bigger engine), it's looking for 20 or more (I have set the max trim before accepting to 20%).
I'm putting this down to (a) increase in displacement, (b) stock Triumph map being lean to begin with for the 2.3L, and (c) differences between Triumph's stock AFR targets and my PCV AT targets.
Also I'm sticking to the standard resolution PCV map for now, I need to build the skeleton first before i flesh it out with a real granular fine resolution map for optimum smoothness.

What AFR's are you heading for? - I seem to remember that using Rob's RBT map he "knocked up" for me, even my stock block wanted the best part of 17%.

I knocked one up too real quick, just used the AFR table that Deano The Dyno Dude made for me several years ago. Zeroed the fuel and trim tables to begin.
Thanks for that info - good to know how much the stock map is lean by. Jogs with my theory about why mine is calling for 20%+.

Before
After
Also a little update on the tuning front, I've worked my way up to about 17-18% throttle now, the autotune has settled down in the low %TP / low RPM area, but is looking for moar fuels as I open it up, which is great.
I'm still abstaining from making fuelling adjustments myself, I want to see exactly what the difference is between 2.3L and 2.5L fuelling-wise, as it develops.

So, we've clocked up 600 miles on the 2.5L stroker, every single one of them in 5-8°C weather but the bike has been a joy to ride for every single one of those miles. It hasn't missed a beat. Cold starts immediate, hot starts immediate and no issue at all. Runs smooth.
Getting 29MPG(US) / 35MPG(UK) on each of the few tanks of gas i burned, this is cruising at average 70mph with a good few accelerations in there to broaden the map.
I've kept it under ~4500rpm and ~60% throttle (having incrementally worked up to that) for this break-in period, this is a screenshot of Autotune's recommendations after a 154 mile ride last weekend;
The break-in service is done, oil was very clean.
Now I can go map it up to 100%. Even at 50% throttle coming out of a slow bend, the thing sounds and pulls like a snarling beast.
Oh! and we have a date with the dyno.... Saturday 22nd, I can't wait

Getting excited about this.
Instead of buying a new GT I am thinking about spending a lot less cash on my Rocket to upgrade the engine with my up-date kit, your 2.5L kit, Lush cams/pistons and ad some high end front suspension cartridges. Now what exhaust could I use ? I have the complete Staintune system off the 2005 basket case, but I think the header is more of a bottleneck then the TORs I have on. TTS has their 50% larger tube header that fits under the stock chrome heat shields. Thinking of using that. comments.
