The stock ECU will not perfectly correct the differences made in the engines new AirFlow/Fuel requirements, but it will still run very very well....
If you want it to run top notch, then yes, you'll need to get it a PC and get it mapped...... the only problem there is....
Finding someone that can map it correctly....

Check with your local road-racers and drag-racers (preferably the ones that win often). They should be able to send you to a good dyno shop.
And, don't forget that Road Racers and Drag Racers usually only put most of their tuning effort into a narrow band, say 3/4 to full throttle.
Real world riding requires much more than that.
