Cummins never tuned a engine like the sound found in the Pulsar's I'm on about above Euro 4, Other examples with the same noise are Euro 4 E400s, Euro 4 Optare Versa's and others.
Without even talking about engines, 14** have a kickdown, Euro 5 regulations stipulates a restricted one, Which is found in the 61 batch upwards.
Euro 1-6 regulation is purely to do with engine emissions and I can't find anything relating to kickdown.
However, Sanders Coaches do list their own 59/10 reg Pulsars as Euro 4: http://www.sanderscoaches.com/about/fleet.aspx
Although like others have mentioned I was always under the impression that all Arriva's Pulsars are Euro 5.
