For all 3 reply's above.
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.
