Like he said.
No use to do tuning unles you can mesure it.
I got a Rapid Bike III fitted.
In short: Its smooth and powerfull now!
You can find the dyno here (large file)

Study it in detail and you see:
Top power available from 6000 rpm and staying there.
Max ref upgraded with 500rpm
Air-fuel optimised
added torque over the entire bandwith..
To continue on the "to dyno or not" topic; This tuner also had a R1200GS from a dutch dealer, that was modified even more (internal engine components). This bike got a lot of attention in magazines etc. He tuned it with the Wunderlich powercontroler. And found it limmited.
The effect was a stunning boost in the mid section, so anyone driving it could say it gave a kick in the bud.
But if you look at that bikes dynochart:
my bike has more torque and power over the entire bandwith exept for about 3 bHp on te very top range.
The "kick in the bud" was actualy a
big dip in the performance until 4000rpm, to give a fast boost up to 6000 rmp. But overal the powerline was below mine
I agreed not to post the comparison dynochart to keep that dealer happy
