Okay UPDATE, Chap brought his car over today, we swapped MAF's and the problem still persisted. When we went for a drive i monitored his fuel psi with my scan gauge, no drops. The cut out is definitively boost related and not misfire/coil...
In my opinion it sounded like the CBV quickly opening and closing letting off pressure. We checked the vac lines they seem fine and he has a brand new TCV.
Were are thinking something to do with the wastegate that's been affecting it since pre-purchase. One of our local volvo quebec members has an ipd adjustment tool, well try and borrow it..
Thank you all for your input. Mucking around with his car tonight has given me the motivation to install my fmic tmr
