yes, holds boost fine normally.
right after this happened, i pulled over, ripped the wire out, back to standard, and it was holding 5 - 6 psi then up to 7 - 8 psi after 4500rpm. always has been fine.
the thing that got me was that it produced very little boost at the time of the 14psi episode.
i'm sure the thing would have wound out to 20psi if i throttled it and didnt pull back.
afterwards, i was a little concerned with the health of the turbo.
i started the car hours later, cold, idling at 1100rpm or whatever cold start is, and gave it a decent rev.
had a look at my exhaust and saw some white/grey smoke.
could this be seals? or just rich cold start ?
no sign of smoke when i got home.
