I sent an email to power commander about the 1st & 2nd gear limiting & there response wasn't conclusive on the way honda have gone about doing the limiting, my guess is fueling will have no effect so fitting a pc alone won't help the 1st & 2nd gear limiting & it is performed with the timing. What you have said makes sense but it would be nice to know exactly what Honda have done.
I found this dyno map that has a 2nd gear run over layed onto 3rd & 4th gear run, you can plainly see the dip & 20hp odd less power in 2nd gear.
yeah that dip doesnt look like fun...
funny this who time i thought the limiting was done with the throttle bodies, not just pulling back igniton timng.
well it makes sence, honda does it to the cbr1000rr and 600rr.
anyways if its timing its a simple fix that any of these companies can make for the vfr...
just look up :
dyno jet ignition module,
TRE
bazzaz z bomb.
all the tuning companes have solutions for this.
almost every suzuki bike has restricted timing.
and honda pulled almost 10 hp off the top of the new us model cbr1000rr to meet noise emissions:

In looking at your hp chart I noticed that you tq and hp did not cross at 5252 rpms, That leads me to beileve that there is some issue with the valididy of this chart.
Hp is defined as (tq X rpm)/5252, therefore the TQ and HP lines must cross at 5252 rpms.
