Tire Pressure

I know someone will have the answer to this one...
Is correct tire pressure more critical in low profile tires, such as those on the IS300?
My tires had lost about 2-3 lbs so I topped them off and I noticed (or thought I noticed) a significant difference in ride and handling.
My IS is the first car I've owned with low profile tires and I was just wondering if small pressure changes can really make a handling difference?

Unless of course that manufacturer is Ford and you have a vehicle equipped w/ Firestones...
