[Biturbos4] No turbos?

[Mark R]

Warning!  If a DV fails, the turbos can overspin.  Also, with differential
in boost pressure, there will be abnormal crankshaft pressures.

Check for codes, to verify is isn't something else.   If you're running
stock style valves, time for an upgrade.  Personally, I've always used and
sold Bailey valves, but that's just one good choice.
