Sorry I was thinking about a different OS. I had to alter a VDF once a while back

but it is a must if you want more than 14.7psi. i wanted to do 2.5 bar but my computer won't run it i guess.

well damn, it doesn't grow. well i guess at least out of boost range its still 10kpa. so part throttle should still be ok. is there any os's i can over ride to my pcm that would work to get a better resolution?
