Dial in the control pressures and adjust base AFR and more ideal AFR's can be achived.

Get closer to ideal AFR's and one will deliver more power.
Yes flow matching adjustments done via the meter head "with injectors fitted in place" as this is the fuel amount going into each cylinder..

Yes can tune closer to ideal AFR's then more power achieved..each cylinder then producing same power as one another in theory can only be a good thing also!
