Psst... Not true. If you disconnect the pressure line or the line going to the wastegate then the wastegate will not open until pre-turbo *exhaust* pressure gets very high. Overboost will occur before that happens.

If you disconnect the line going to the the boost solenoid (and plug it), then the turbo reverts to wastegate pressure. (This assumes stock bleeder-type boost control).

Jesubi11, which line did you disconnect?
