The static pressure when the pump is off is the high side...you indicated 48 pounds, so (since the gauges aren't super accurate), I'd guess that your turn off pressure is set at 50. There is typically a 20 pound difference, so it would turn on at 30. Just run some water and watch the pressure gauge...it will probably cycle between those two numbers.
You could try bumping the pressure to 60/40 from what you have. You'd need to adjust the bladder tank pressure up to about 38 pounds though. I'm not sure if you would need a new pressure switch...as I'm not sure if both the turn-on/off are adjustable. One of the pros can answer that.
An alternative might be to replace your constant speed pump (cycle on/off) with a continuous pressure pump. This will likely cost more to both operate and purchase, but you can get one to provide pretty much whatever 'normal' pressure you want in the house.
My unprofessional experience.
