The w bodies and minivans had the 4t65 trans which allow for better programming to allow more power.... it's the gearing and programming, same as the grand am gt has an extra couple hp then the alero and grand am se.... the alero is a 3.05 final drive ratio vs the gt which is a 3.29 final drive....
