no boost after returning from a weeks holiday

Hi all,



Just driven my 45 after a weeks holiday so the car has been sat idle and I can tell its a bit chilly now.



Anyway I noticed in low gears more of a whooshing noise and when I get to third there was no noticeable boost kick that I so much enjoy.



I pulled over and plugged in my reader, kept driving and boost never goes above 2 psi.



I've checked the actuator is still attached and it is. Not sure if it could be sticking? I did get intermittent stutter during hard acceleration a few months back but it seemed to stop.



I'm running sdi s, no egr, boost was set to 19, paperclip mod



Any ideas? I've just had a new starter motor and coolant pipes so will pain me if even more work is required!



Thanks
