Of course depends on every situation, but yes you want to keep FP up. Once you hit the dip into the 4x range then I would consider the upgrade and of course base that on your future goals. This does not really matter so much for boost or N/A, it's a generic comment. Fuel pressure is one of the lifelines to the motor, this is nothing to play around with.
