Here was my request.

"
Letter #3798
Title: Include Non USDM Engines
Request: Please include non US Market engines. I suggest that these engine packages be approved on a case by case basis. Require a VTS to be generated and that those packages can only run by that "STU" VTS. Competitors will be required to sumit documentation to support requested classifications."

I did this to officalize it and get it into the system. Keep in mind that this was my suggestion, not writen into law. My thinking is that all non US Market engine packages would need to have a VTS, just like an ex WC touring car.
