I would definetlly start with a good dyno tune to get a good map and tell the tuner you have a problem with abrupt throttle mid corner. You could also take off tank and air box and lay the bike over on its side and operate the throttle to see if any thing is binding or sticking.
My bike also had abrupt mid corner throttle responce, although both ways. Part of the problem is the stock ecu is set-up for emissions so on decell (off throttle) the fuel gets shut off to the injectors, so when you go to roll the throttle back on you go from no fuel to lots of fuel for the anticitated acceleration. I have heard good tuners can tune that out, but i got an HRC ecu for my 07 race bike and that totally got rid of all that abruptness, my favorate mod to the bike so far. Made pushing it hard in corners, when you're just on the edge of traction, so much easier and confidance inspiring. The HRC ecu also bumps the idle speed up to 2200rpm from the 1400rpm stock, which also helps. You could use ECU-unleashed who can muck with your stock ecu and bump up the idle speed and tune out that abruptness.
I doubt if there's an ignition problem.
