1986-1988 stangs had speed density. This means that the computer relies on stuff like maniflod pressure to tell it how much air it is taking in. 1089 and up had mass air meters that measure the air coming in. the speed density cars are faster stock for stock. But with speed desity stuff like intakes and exhaust systems can mess up drivablty and you CAN'T add stuff like cams
