Just wondering???

Right,
say there was a turbo gone on the twin turbo, would the car boost as normal, then drop off at the V.O.D. and spool up and boost again at the same boost???
Could there be say 0.3bar boost creep??? hence making you think that there is nothin wrong, i'm only querying and haven't noticed a problem (no smoke,no jumpyness,perfect driving), Car just does not seem too be boosting right. I can explain better if needs be. (This is best i can first time around)

AFAIK if primary turbo is gone then she will still boost after VOD but will be reduced pressure, and if secondary is gone then you'll get perfect primary but boost less on secondary when both kick in.

If one is gone though it may be smokey or may have vibrations but maybe someone can correct me if i'm wrong

As above - I had a fairly major crack in the manifold just behind the primary last year, meant almost no pressure building in the primary - secondary seemed fine though, just meant feck all acceleration up until you hit the secondary. Oh that and a bunch of check engine errors.
