Could be defective chip, but often the Diverter Valve (was that what you meant by BV?) or Throttle Body Boot (TBB) will break due to the increased boost. Both of those should be replaced with heavy duty when chipped. See my signature for what I used (I chipped at 70k and now have 126k on the car) but there are several equally good alternatives. Search the forum.
