I havent noticed any performance issues and the intermittent .10 bar below pressure which possibly is the failing regulator or just sensor noise. Ill be doing more testing but i dont believe any actual starving is going on. I could somewhat easily just remove it and test.. but i think either way the regulator is likely bad and needs to be replaced anyway. The filter has like 250 gph and i believe the s65 only requires like 40? Im not sure the effects on pressure the filter could have assuming everything else is working.
