Only if the top if the wastegate is at atmospheric (and then it would
depend on altitude).  If the chip were to flip the wastegate solenoid
over such that manifold pressure is on top as well as the bottom of
the wastegate, the spring becomes irrelevant... you could then
wait for boost to rise before doing the normal control of the
fequency valve - switching back and forth between manifold pressure
and pre-turbo (slight vacuum).

So it _can_ be done with the chip, just as it can be done with
a pressure regulator connected in place of the solenoid, or
indeed with a different spring (though as you point out later,
such a spring may prevent the wastegate opening fully).
