Andy,

Was the power gain after the air box modification with the same jetting?

I'm sorry, but I can't/won't comment on the jetting of any particular setup. Besides, there are no jetting notes on the run file of that bike, and it was done way back in 2006 at our very first ever Dyno Day, so there's no hope of me remembering specifics! As with all topics of this type, I will simply say "every situation is different. Always check the jetting after every mod!"

Is the loss in power in bottom end/mid range due to race exhausts being free flowing and therefore a loss in back pressure?

No, not really. It's due to the physical shape of the expansion chamber.
