I had a similar thing happen with my GTI after having it mapped, took it back to the tuners and straight away they said it was low fuel pressure, they fitted a new fuel filter and it fixed it, (there's a pressure regulator inside the filter), not sure if your filter would be the same though! Cheap part so worth a go!
