I don't know why your computer says that link is a virus I just tried the link and it works fine. Sorry if something looks funny but they are or were last year a legitimate company and was the first to post before and after Dyno results.I have not talked to anyone at SI since just after I received my ECU back from them. I live in Texas and have nothing to do with them other than being a customer and I have been around this site for a long time and would not knowingly post misleading information or a link to a computer virus.
