Focus st250 big turbo issues

Good day guys, I know I just joined but I've recently gotten hold of a mk3 focus st250, the vehicle is fully modified in such that it's got the following 

Cobb AP, GARRET Gtx3076 turbo with all supporting modifications, aem stage 2 water meth kit, stage 2 pipe cams and Rev kit, auxiliary fuel kit etc the list can go on. 

 

Reason for the post is that I've just done the cylinder head and the following faults come up:

P0344 

P0340

P0246 

The first 2 faults are related to the camshaft sensor circuit on the intake side, I have visually inspected the wiring myself and all looks fine, I've replaced the camshaft sensor. 

I've even taken off the tlcalve cover to inspect the sensor ring all is okay still. 

The 3rd code is related to the boost pressure solenoid A which is situated on the top of the valve cover I found wires damaged and repaired them still no luck. 

 

Any advice please has anyone had this issue?
