Thanks for the reply.

My car is an 03 plate, so pre face lift. Yes I have fitted colder plugs, the GTT iridium plugs to be exact. The pulley does seem to be doing alot in terms of power, if the car was 163bhp standard then the pulley and the air filter have increased bhp by 33, so I'm quite impressed that this is close to an older JCW. Although I didnt notice any difference after fitting the JCW M'sport air filter so again the increase is all down to the pulley.

I certainly noticed a big difference after having the pulley fitted, both in terms of extra power, better torque right through the revs and of course more "whine"

Sorry I cant help more on your ECU query, but I have noticed Roland from GTT has mentioned that most cars dont require a remap as the standard ecu is very adaptable.
