Are you referring to 'low' as being lower than it used to be before the synth switch, or at the bottom of the gauge / needle doesn't move?
If you stick a real mechanical gauge on there and have around 7-10 psi at idle warm and between 36-71 psi at 3500 rpm's, you should be fine. If you don't, it could be the pump is worn, the crank or rod bearings are worn or the oil is too thin for your conditions.

it's not a big deal. you usually have less pressure with synthetic, as it's slightly thinner (despite having the same weight rating). As long as you have oil flowing, it won't be a problem.
My motor on 5w-30 synthetic usually sits just below the 1/4 mark on the stock oil pressure gauge at idle.
