Not so much dead but not right at all

Hi
Yeah I have a boost controller but I'm not looking to up the boost any more
I've done the max fuel screw before but it smokes heavily till boost builds
As I've set it all back to stock and have got the boost set to 12psi I was looking to add just a touch more fuel when on boost as I feel it would benefit from that rather that the whole way through the rev range
From looking at the pump I presume the doughnut shaped diphram housing is a boost compensator and has a bolt and lock nut going into the top of it
So I was wondering if adjusting the bolt on that would trick it into thinking I have more boost and add the desired amount of fuel I require
If so what way do I turn the bolt to make it think I have more boost
Thanks for everyones input
