Well a completely counter productive few weeks.
Popped back to MRC to address the problems, Doug took her inside and logged it on the rollers a few times measuring a few different blocks.
Now i don't have the logs yet, but suffice to say it was maxing out at 150gs, Doug said it was pulling 170 odd when they mapped it and suggested the MAF was goosed.
Luckily i had the VR6 element in the boot and swapped that in... That got me to 160, but then the scalling would have been out as the map was scaled to utilise a VR6 housing and AJL sensor.
So, i came away a few gallons of petrol lighter, but the car no closer to being fixed.
As the fault seems to be something that developed from the initial mapping session to my drive home, i now have to pay for any subsequent map checks and tweaks.
GULP !!
I have since bought a new MAF from VW @ £102, i tweaked the method of fitting the MAF into the airbox, added a cold air feed and put the brand new element in... It's the ****** same...BOOOHOOOOO 150 GS @ 6k ish

Not best pleased TBH, but hey. The splutter @ 5 k ish seems to still be there and can be seen on the log by a drop in air flow.
I have also changed all of the hose clips to HCS Hi Grips instead of the Mikalor bolt style ones. I am hoping that maybe @ 1.5 bar i have a leak i perhaps didn't have before...
Need to check that, Job for tomorrow now
