If changing the actuator fixes your problem you should at least call the company you got it from and let them know they sent a defective actuator. Any business with integrity would send a new one and possibly spare themselves from sending out other bad actuators.
I still think you should find out how much boost it is actually making.

I got a hold of drift motion and told them my problem they wanted me to send it back but cant relay do that so I told him If i can send them the actuator and will do today their going to check it out
