Welcome,
Lots of discussions here about tire air pressure. An interesting one just a couple of days ago so filter on "air" and the past week. The consensus is normally go to maximum that is "printed/stamped" into the tire. The data on the door or owners manual is what Saturn wants you to run. The data on the tire is the maximum that the tire manufactor recommends.
The air that comes into the filter box is normally from down low near the bumper/tire well somewhere. It is trying to get cold air. Just unhooking that hose from the box will get you air from inside the engine compartment. That is warmer then "outside" air and might be a good place to start.
Read up on "grill blocks" as well. It is another "low hanging fruit" that helps when you are not in the middle of the desert.
Also look in the garage for other Saturn owners and then search out their modifications/information.
