Ok, quick update. Changed the solenoid and all was ok for a few days as the car was behaving at the time anyway. Then yesterday on my way home i was only achieving 8psi. Have borrowed a maf from Partmaster (cheers Dave) but still no difference. However, on my way to work this evening, making my way down the 23. Tried putting my foot down a couple of times and no change. Tried it once more a few minutes later and the boost gradually crept up to full power. Then got to work, put my MAF back in and took a quick blast up the road and its still behaving itself so i guess the maf isn't the issue???

This makes me think that either a pipe is clogging up then gradually blowing through, or something is sticking open/shut and after a bit of persuasion (my right foot on the happy pedal) it lets go and does what its meant to.

Please, ideas anyone? Was thinking maybe actuator related... any way i can test this? Or is there any diagnostic tool that can be plugged into the car? I'll give anything a go once
