There is no actual effect or power up.
You multiply both the stat and the costs by 10, so they balance out. The only impact is that by doing so you are putting everything on the same scale, which makes making things like Action Penalities and damage calculations easier to apply.
At least, I have toned back my house rules ;)
I am pretty much just focussed on unifying the way the mechanics are expressed where doing so has no impact to the underlying system.
