Around 225ft/lbs. I'm pulling out a little more timing now. I think the torque figure on my last dyno was 218ft/lbs.

Thanks. Aren't the Air/Fuel lines supposed to be straight and online with each other?

Not necessarily. The AFR line represents the AFR that the tuner programmed to safely get the best power out of the bike at various rpm's based on his learned understanding of the power curve as he makes multiple dyno pulls.
Ignore the red AFR line. It's the before and is terrible. The blue one dips low (goes rich) at around 3K rpm where the most torque is being made to keep the engine safe (more rich = more cool= less chance for detonation) then comes up a bit and remains fairly flat all the way up to redline but slowly dips down as rpm's increase to keep things safe as it makes more and more HP. So it is rich where it is making the most torque and HP and leans out right to where it needs to be for the rest of the power band to make the most power. Too rich is just as power robbing as too lean but a little too rich is a safe bet with forced induction.

Gotcha. Thanks for the explanation. Did you install the kit? How much did it set you back if you don't mind me asking.

It was on the bike when I bought it. Pretty sure the kits at the time were around $5500. You'd have to call turbo connection (that link above) and see what they're going for now with that new turbo. Looks like it puts out just a bit more power than what I've got as well.
