[Biturbos4] smoke at high revs

[Wilson Northrup]

what color is the smoke?  white? blue?
Check your coolant, any missing?
Did you pull a plug? any oil inside?
Check your oil, are you low?

if no to those two and the smoke is blue, it could be something related 
to the turbo, for example, the turbo seal.
