Yes, I have an SVT. However, it's the fuel and spark maps that I want. It would seem to be much easier to change the redline than to change fuel and spark maps. Although it is true that it has been optimized for best performance, that best peformance was for a 2.5L and not a 3L. I figure this, worse case, it's easy to repin a connector should I have to go back to the 2.5L PCM. I want this rebuild to provide me with a durable and reliable engine that can give me years of faithful service.
