Be careful changing your well pumps pressure, it can damage the pump. An electric motor is designed for only so many starts per hour or it overheats, this is usually like 6 starts per hour, They also have what are called its service factor and its duty cycle. The pressure switch is set at 35 psi for a reason. Besides that, raising the well pump pressure is almost always more expensive than buying a dedicated RO booster pump since this is the only piece of equipment that needs the additional pressure.
I started my water career as a well driller back in the early 1970's then later as a pump installer and well development specialist for the next 5 years and things really haven't changed much since as far as wells, pumps and motors.
