Erratic Fuel Pressure

Last summer I installed a Fass DDRP into my 98.5. Until recently fuel pressure with the new LP has been a steady 16 lbs at idle and 10 @WOT. Within the last week I'm noticing fuel pressure readings between 19 and 20 lbs at idle, while WOT and steady driving @2200 rpm have stayed consistent. Anyone else experience this type of jump in idle fuel pressure? Should this increase in pressure at idle be a concern?
