Mark, I've got 7 or so coil-packs lying around - not sure if they're all 100% good, I did replace them for a reason but you're welcome to borrow. As a side note - have you checked your vacuum/boost pipes that run to the wastegate cans? When I had my 32 GTR one of mine blocked up and caused the BOV(s) to flutter continuously under boost (and also caused over-boosting), wasn't exactly easy to diagnose though.
