Have you checked to see if you can install heavier valve springs in your Ford? I know that in order to install an exhaust brake in my '98 12 valve Cummins I also have to install heavier springs (Cummins sells 60# springs). The other reality is that the automatic trans. in my '98 will never hold the truck back like the 6 speed in my '06. But it no doubt will help.
