Are you saying that you've DRIVEN the car at WOT and confirmed that your secondaries do not open? I'm guessing that is the case based on your "paper clip" remark, because you know they won't (or at least, shouldn't) open by just revving the engine while parked.

If so, does the car run out of steam on top or is it still pulling hard through the expected rev. range? The thing about vacuum seconds is that they'll only open when the engine asks them to.
