P006B & no low speed boost

I have a 2008 F250 6.4 and I keep getting a P006B, I replaced the MAP and cleaned the EBP and tube. Also now I'm getting a P2263 and a P2563. I'm not getting much boost at low rpm's. Good high speed performance. I'm running a Mini Max on HD300 with the dpf deleted and a K&N cold air. Anyone have this problem or know a fix?

you should check the turbocharger actuator linkage to see if you can move it with your hand, key off. You should be able to push or pull it 1 direction, then it should spring back to its starting position. Id also recommend unplugging the electrical connector to the turbo and checking for power. if your looking at the connector with the lock/clip upwards, the pin all the way to the right should have power, key on. I have seen more problems caused by tuners, than I have seen turbocharger actuator electrical problems, so it could be your programmer.

I can move the actuator ok. I haven't checked for power yet but I will. But I went to clean my EBP sensor again and I set my tuner to read the EBP and with key on engine off I'm reading 44, driving it goes up to around 58-60 but never comes down under 44 even with engine off. think will replace he sensors and see what happens.

Fixed! I put a new EBP sensor in and now the turbo is working great, my truck runs like new.
I guess I should have checked the pressure reading before I started this thread. Thanks for
the help anyway.
