I don't know if this is universal, but you may be able to purchase a programmed chip to let out more performance and/or better gas milage. Off-hand, I don't know of any sites to link to that can do this for you, but I know there's a niche market out there. Prices vary, but some of the prices I saw were $200-400...but that might be worth it if you don't feel like hosing your car.
