The Power Commander EX is a unit that was developed for those areas of the country that have more stringent emission regulations, i.e. California. Those areas do not allow devices that change the fuel curve in certain areas on pollution controlled vehicles legally driven on the street. Therefore the EX unit does not allow for fuel changes to be made in a substantial area (lower RPM and throttle positions) of the fuel map in order to gain legal status in those places. This area is grayed out in the fuel map. The race ready Power Commander line allows for fuel changes to be made in the entire map as well as offering several more features which are omitted from the EX units. The Race Ready unit is differentiated from the EX street approved unit, in that it can make a substantial difference in power and performance, as well as providing a cooler running motor. We do not specifically recommend one unit or the other, but leave that up to the individual customer to determine which unit best fits their needs and local regulations prior to purchase.
