Right. You'd have to get rid of a lot more weight to feel anything.
Me... I'm in pretty much the same boat. I just had to come to grips with the fact that my car is good on gas, good on insurance, but really bad on power. I don't have to use the freeways too much so I get around fine on the surface streets.
I put an intake, exhaust, plugs, wires, pro kit, and strut bars... wheels and tires, and I gotta say the car is a lot better than it was stock. Tho still FAR from being a sports car.
