if i do a 300-6 build will the e4od transmission still shift at the usual shift points or will it kinda just correct itself becuase if it shifts at lets say 3500 rpms and i build it and the cams operation range is between 1500 and 4500 rpms it will shift too soon how can i change this because they dont make programmers or anything for a 92 f150 with speed density ecm.
