I personally sent them an e-mail asking for valve toss data - they had none. In fact, it is my understanding these cams have never been installed and run on a Duratec.
They also replied with something along the lines of "we are familiar with the Duratec here in Europe, but have not worked on one from the states". I did not inquire any further after that statement......
I can forward the e-mails, if you want to start the process over......
