Flashing Pro's & Cons

[Batfink]

The maps on the ECU which "tune" your bike have been done for nearly every mod thought of for the busa.... and a lot not thought of too LOL
As long as your Flashing guy knows what you have done/are doing to your bike he can put int he correct map(s) that takes into account the changes (eg, full system yoshi pips, K&N filter, etc..). From what I undertstand you can squeeze a tiny bit more out of a customised dyno tune/flash due to the micro differences between individual bikes but the final effect is only something you will notice on a print out graph (tell me if I am wrong peeps).
You can also use your mode switch to have 3 seperate maps for various senario's, it doesn't have to be the factory setup of power restrictions lol There is a mod which can increase these 3 modes to 6. Some have changed the modes to suit different fuels, allowing better economy and wider variety of fuel use while touring.
I was a big Power Commander (PC) user before I got into busas but after reading and chatting with people here like Camel not only have I been converted for the busa but any bike where you can manipulate the ECU
