my gti turbo kicks in at about 2000rpm and boosts up to 6000rpm after that is just flat??!! is this supposed to be or will others boost all the way to 6800rpm.
my old scooby used to go all the way through the gears to rev limit holding the boost till gear change, i also drove my mates golf 1.8t last night with revo remap, his is no where near as quick as mine but his holds the boost to the limit.
is there anything that will help this (d.v valve....intake...miltek)??
views would be appreciated. 
Once remapped that's about right. I think what you're feeling is the lack of torque at high revs. This is greatly exaggerated after a remap (Revo used as example) as you have a massive increase in torque at 3.5k and its just a steep decline from then on
BHP increases at a good rate until around 5k and then it starts to level off, so with the combination of this, the decline in torque and that fantastic midrange rush, it can sometimes feel a bit limp above 5.5k rpm. The ed30 is much better up top as its larger turbo will provide a higher level of boost at higher rpm.
I've got mine a little better by doing some data logging with VAGCOM and altering boost/timing with an sps switch.
A Milltek and hi flow filter will make things a little better but to get the most out of these you will need a remap designed around these 2 items installed. e.g Revo stage 2.
