Any detail report or link about the Sportec RS550 or RS600?

I am very interested on these 2 tuning...
Thinking about an upgrade!
But the limited reports on those 2 upgrades...
Any thought is appreciated!

If you do a search there is one with the Sportec vs MTM.

You can always e-mail them for the article or go to their website I think its in a pdf file.
