Smith,Congratulations ot your new car and welcome to our club!
Stillen makes a great eninge chip for your model year.They also make a (less popular) TCU.
I would not botehr putting in aftermarket intake and exhaust as the factory ones are very well designed and run pretty free to begin with.
One good performance "mod" that's iften overlooekd:Keep the car in great shape as per plugs, injectors ect.
An maintenance act, as simple as a thourough throttle body cleaning (maybe plenum too) can add real power to a higher mile car.
