It sounds to me like this is a wicked piece. I would assume that for the ultimate performance, you would need to remove the dash to access the bolts installed through the firewall. I don't think that any sheetmetal screws would hold up.
BTW, my impression of TEP is also not a good one. I have seen their Z's at various drag race events and they easily break. They like to use the Electromotive TEC II, but it seems that they don't know how to program it becuase the cars I have seen from their shops run overly rich. Also, a friend of mine bought their intercooler piping for his Chrysler Conquest TSI, which they claim to specialize in, and it didn't fit at all. It was really crappy. He had to send it back for modifications. Anyway, just an observation.
