Bought this car as a factory cobra, when I went to see it/buy it, I discovered it had a Kenne Bell supercharger on it. In the glove box was a sct computer that plugs into the obd port, the salesman,I got the car from a Ford Dealer, told me could turn up to a 1000 hp. In the trunk fastend to the drivers side is a little black box about 2 inches square with two wires coming out of it with numbers from 10 to 30 on it and a dial currently set at 16 ,also says Kenne Bell on it, currently set at,as I was told, 420 hp at the tires. Not sure just what i got , but i'm working on it. Got low idle missfire, under 2000 rpm, spark plugs maybe? and speed sensor is not working right
