Boostspike problem

Greetings, I have a Fiesta st200 mk7 I have installed a VT330R, and I'm over boosting right when I press the gas pedal. The boost level is set to 1.5 bar and it spikes at the beginning to 1.8 bar then set to the right boost level but goes into limp mode if it happens more than once (limp mode doesn't give more than 0.5 bar shown in the video). I checked the actuator and changed the solenoid also did a boost leak test everything looks fine but still have this problem. Need some help on this topic. I attached videos of what this looks like. I'm in the phase of removing the turbo and looking into any type of damage in the wastegate system.
