It depends what you want to gain from it. If you looking at adding more power then it's just an endless worm hole, there will always be little mods and changes to eek out more bhp. If that's what your looking at then your best to do all the physical mods before you got get the map done, otherwise you'll be back at the dyno centre everytime you change something.
If your hoping to smooth out power delivery and maybe gain some bhp then I'd say it's worth the ECU flash. If you have a snatchy throttle then that will be all but eliminated, theres a few other bits that can be done ( like 1st gear delimitation, raise red line etc) but most are things you wouldnt notice
If you do decided to get a flash or a PC5 then I'd make sure you get an aftermarket can, decat the downpipes, gut the airbox and add a higher flowing air filter other wise you'll be missing out on the main performance benefits
In my opinion if your happy with the bike as is, and you say you wont be keeping it overly long then I would just leave it as is. It's a lot of money to spend for very little gain, especially if your just gonna change it in a years time
