Base boost - at witts end!!!

I've been having a base boost problem for a while now and after checking the BB for most (if not all) possible causes and solutions, I'm none the wiser and my car is still only showing 4psi!!!!
Here is a list of the things I've done -
New blow off valve
Checked vaccum hoses for leaks
BCP solenoid - replaced with another - albeit used one
New plugs and gaps
Knock sensor - unbolted from engine and wraped in newspaper so it wouldn't detect knock
Replaced turbo - wastegate works good (turbo was replaced AFTER base boost problem)
No intake leaks from the AMM to throttle body.
I'm lost - Is there any way of checking the BCP without just replacing it. I just don't want to buy a new one when I don't even know if the old one is bad.
HELP needed desparately
Thanks
