Sounds like the ECU is in limp home mode for some reason ... reset ECU first.

Also could it be that the pipes from the boost solenoid to the compressor nozzle and WG are the wrong way round?!

I had a similar problem with the boost and it was down to my boost solenoide, changed it to the 3 port solenoide and the boost came back up to 1.2 bar. Also pops and bangs, have u got a dump valve fitted? i had a problem with loosing pressure through it due to the spring being weak, which caused pops and bangs.

Yes i do have a bailys dump valve...cud i blank it off and try that or would that do damage?

Did you check the spark plugs (and coil packs if any) when you replaced the engine? Misfiring as boost comes on might be caused by one of these.
