Please see below a log of 3rd gear from 2000revs up to 5000revs
I read this as the car is asking for the same amount of boost all the way through and only asks for more boost at 295 to 303 seconds, this is my first crack at this so please bear with me and help me if you can.
What could cause this?

Something broken there dude. There is no requested boost at all until 3000 rpm for some reason, the 1010mb is just atmospheric pressure. Any fault codes at all? Your MAF readings appear to be screwy before 3000rpm too. Was your foot flat to the floor on the pedal from 2000 to 5000?
It'd be handy if you could get more logs but individual values, so that you get a higher sample rate. Logging 3 MVB's at once is a bit slow on mk4 ecus. Fire the csv files over to me topher@golfgti.co.uk and i can chart them to make a bit more sense for you.

Nice one, Ill do it again this evening.
Much appreciated
