I know you said you don't want to adjust your rev limit, but I would. Just nudge it up a couple hundred RPMs to match the ITR's limit, it'll sit nicely with the cams.
Would also suggest adding a Skunk2 intake manifold since you're going to be pulling the engine out anyway. It'll play nice with your new setup. And you'll get rid of that god awful GSR manifold.

I hate that thing.
As the snoop said, a vafc CAN handle what you're planning, but you'll be pushing its limits and would be served much better by something along the lines of Hondata.
