False. A wastegate with no line attatched will not open, creating more boost, eventually maxxing out the turbocharger's boost capabilities. And, exhaust pressure won't open a wastegate if it's pushing against the actuator.

The wastegate reduces boost, not increases boost.
OP, more likely causes of your problem are boost leak and/or bad turbocharger.
