The GTM uses a Rotrex SC where the Stillen uses a Vortech V3. The rotrex is technology is relatively new compared to standard centrifugal superchargers.
Little off topic Tony, but do you know which Rotrex unit he is using on the car? C38-61, C38-71, or the C38-81? Also what was his target hp?
I too find it hard to believe that headers can be the cause of this issue...
