If I remember correctly the coarse adjustment is a ball and spring adjustment and the fine adjustment is a bleeder type adjustment. Both should do the same thing. I would just focus on getting the ball and spring where you want it.

It has a ball-and-spring design for fine tuning, combined with a bleed valve for coarse adjustment. Use the brass adjustment to increase boost to within 1psi of where you want it to be and then use the blue adjustment to fine tune it.
If you add too much boost using the blue adjustment, you will get inconsistent boost levels in the higher gears
