The 1996 Ford Mustang is available in six models: Mustang (base), Cobra and GT, each as either a 2-door coupe or convertible. Standard features include dual airbags, power mirrors, tilt steering wheel, tinted glass, AM/FM stereo, power 4-wheel disc brakes, a 5-speed manual transmission and a 3.8-liter 150-horsepower V6 engine. The GT has a 4.6-liter V8 engine with 215 horsepower. The Cobra has a 305-horsepower V8

Correct me if im wrong but he prob. wonte be seeing much since the GT stock only makes 215hp. Best advice sell the car and get a 99-04 so you atleast sart out at 260 or better do the PI heads upgrade so your not getting beat by hondas.
