positrac and possibly a higher numerical gear ratio. a 3" y-pipe would make more sense since you have a 3" intermediate pipe.

I am guessing that I am making about 240-250 hp.

Ever had your car to the track?

Is your intake manifold stock? If so get a better one. That alone made a 0.8 second and 2 mph difference on my car.
