Looks like everyone's reading is different. I finally took my car out for a drive since i wrote this post, been sick in bed. Assuming all the hoses were good, I gave it a go.
Soon as I turned it on, I realised the MFD was displaying the oil temp I had 4 days ago, which is a bit odd, normally it displays - - since there is no recording yet.
Anyway got to the servo, turned the car off, turned it back on and the oil was back to normal -- good. Think the car needed a reset, don't know!
First gear .96
Second 1.02
Third (not enough road)
Did that several times, pretty much identical recordings, so maybe after the service it just needed to be switched off or something. Unless when its hot outside and it has been driven hard, it automatically reduces the amount of boost. Because during the service of the car, it was a really hot day and the car had been on for while and a bit of hard driving was used too.
