Reg,
when I had the bike dynoed it was set up for gas mileage. the end result was 140 hp/141 tq. on this tune. The tuner gave me a much flatter power band from 2200rpm to 5900rpm. that's why it feels much crisper. I have a more usable power band with this tune and much better gas mileage. I tuned the bike with a car tire on the back, since this is what I run full time now. my speedo constant is now at 3325 for odometer correction with a 205/55-16 car tire. I'm running 3 k&n's under the bear claw. am also running 15 discs' and closed end cap on the super trap can,so your set up with the short stacks should breath a little better than what I have. I would run yours' 12/14 disc with closed end cap and see how that works out. If you run with the can open, use 2/3 discs on the back just to keep the scavenge velocity up to par. don't run with an open can on the open road,only at the drag strip or for bar hopping/ street fighting i/e stop to stop light. You might be running to lean for open road use with the open can..... my recommendations for a car tire are already known to you.
hope this helps,now open the can up and make some short hard hops.... then let me know what you think....
