hey mate. you can get a Device Called Dreamscience which you can tune your
ECU off. if you visit
www.dreamscience.net i believe it is or search for it in Google (should be a UK company) they are really good tune devices for the Eurofords. You may have to get it custom tuned here thuogh. Otherwise your alternative is to take it to Autotech in granville and get a UNIchip.
