^^^ very good point ! Make sure its super unleaded and not jst any super make sure either shell...(best imo) or bp dnt
Use tesco its nowhere near as good will run but not very well

When u get the dizzee and rotar arm pop it on an take it out ...did u shine a light down the plug holes incase there is water down there standard leads are prone to let water in that comes through the scoop

It cant be fuel cutting can it when i have a greedy ecu or can it
Best way to explain it is

Say if im in 3rd gear at 3000 revs and build boost up then put foot down its fine
And if im in 3rd gear at 4000 revs and just put foot down it judders
Changed all leads plugs dizzy rotor arm oil filter oil on shell v power now

could be a mapping issue,

i'm assuming its still doing it?? could be a faulty map sensor,

considering td are only an hour away its worth taking it back to them mate, least then you get an expert opinion looking at it, rather than us guessing over the internet god knows how many miles away,
