It is not quite as good as a Motec, for certain, and you should choose your EMS with consideration for the community support in mind. The Mustang community definitely does not have the same level of community support for the AEM as the BS3 or FAST. Also, consider the mileage of the car, and the heat that the factory harness has been subjected to already. For a higher mileage car, I would have put the new harness in and gone with a FAST, but for my low mileage Mustang, with its harness in good shape, I liked the PnP of the AEM.
thanks, i think that was one of the best responses yet
