spec1 Ko3 mapping should be around 18psi peak and held around 14-15psi with ve tail as the rpm raise. As Topher said old and weak, I thin he was talking about the turbo and not me? lol A week actuator is going to be the issue here me thinks, but the good news is that we have a unique k03 & ko3s actuator spring upgrade kit comming out soon which will fit to you current oem unit, so no need to splash out loads of money and remove the turbo. For the mean time you can try to add a little more pre load on the actuator by adjusting the nuts on the rod.
