Not Ranked
Regarding the Roush plate, my motor dynoed at 561.8hp and my motor plate says 561hp as well as the torque # it dynoed at, the installer name and the date. I have never heard of generic plates. There have been some very good suggestions in this thread regarding possible problems. I would start with the easiest and work from there.
