i'd call whoever tuned the bike because you have to take into account the compression ratio,fuel mapping/fpr adjustment,fuel ratio,timing retard/advance,etc.
if you up the boost and are outta fuel range you'll run lean and detonate and if yer not running forged pistons then you just put a hole in the hyperutectics

I have been running turbo harleys since 96. I have the Aerocharger turbo on 2 evos and my vrod and love them.
yes you can up the boost but there are trade offs. going over 10psi for everyday riding is asking for trouble dont ask how i know.
I have my turbo evo,s setup for 6-8 and 8-10 and have over 100,000 combined miles without any problems. I have my vrod set at 7-8 psi for reliability with just under 10,000 trouble free miles. Trust me you wont know the difference between 9 and 7 psi unless you are on the dyno or race.

You can turn up the boost. Even with a good tune, you'll fry it if you push it too hard though over distance... so do you want a bike for the 1/4 mile or for the street? Getting that intercooler would allow you to run a higher boost... so would lowering the compression on the engine.
The simple answer is "No", you can't just turn up the boost and expect it to be okay. You have to have a new map for the increased boost, and you need to think about how you will be using the bike.
