Boost is down !

Hi all

I have just got my car back from getting new clutch full service air intake and new custom downpipe as well as a few other little bits, the car is going damn well and running well but when I sent the car into the shop it was boosting 16psi (with a full exhaust) and now I have got it back its only boosting 10 WTF

Anybody heard of this before is this an easy fix ??

All help is appreciated

Cheers

boost leak/loose/split intercooler hose most likely.

sounds like the intake wasnt put on properly...

With a new DP you should actually be seeing more boost if anything...
