Yeah what are your WDCs? You should have them turned down to 0 for 15psi and alittle more for more. If you kept them the same and just swapped out the wastegate actuator I'd guess you'd be boosting almost double your targets. On the stock unit with a stage 1, I"m getting 16psi@3500rpm with only 60%WDC.
