I've got a complete airbox incl velocity stacks. Don't really want to split as I don't think the airbox without them will be very saleable.

What do you want? Short RSV or long Tuono stacks?

As a very very rough guide, for every increase in height of 30mm you lower the point of peak torque by 1000rpm. For my dual stacks, the bottom one is the standard Tuono height, and then the extra top part is 30mm higher again.

doesn’t apply in the case of the double stacks for some reason probably the gap between the 2
these are proven to increase power through the rev range i definitely want to try some

I found that I could run a gear higher and it would pull from lower rpms. I don't have a dyno to confirm this other than my butt dyno, so no figures given.
