Hi,
Having been in exactly the same positions s you.. With a nice shiny ed30 ready to be ruined/made awesome..
Agree with getting everything checked out first, made sure its as good under the hood as you think it is before you start..
Then..
I did a revo stage 1 remap first, accompanied with a new forge DV.
Great mod, just opens the car up, not crazy quick, but pretty quick.. You still get sound changes from the exhaust note, Nd a great downshift blip from the dsg.
Then save up while you're enjoying the ride, cos in about 3 months you'll be wanting a full turbo back exhaust, intake, and an updated fuel pump and a stage 2+, then you'll have an itch about brakes...
Good luck with what you decide to do..
