BD sells HD actuators that are adjustable.I seem to recall that their super B (s300) wastegate started to open with 40-42 psi applied to the diaphram and that was when testing a new turbo on the bench.
The only problem with heavy wastegate actuator springs is that they can put too much stress on the shaft that operates the the wastegate.Then of course higher than stock EGT's only help make things worse.The shaft will twist and then you loose boost more and more as time goes by.
