I thought exactly th same thing, check out http://www.mtechautomotive.co.uk/engine-management/ I gave them a ring and they are by no means unprofessional. They only supply freshly/brand new built up ecu's which are done by themselves which are also warrantied. Bare in mind some ecu's are manufactured abroad in conditions no knows about. They have full mapping facilities with the use of a barnd new turbo dynamics rr. Before you rule them out give them a ring to sound them out. You may be impressed, or you may not but at least you would a good idea of exactly what you are dealing with, im still to make my mind up but I think its either omex 600 if I can afford it only for the reason a friend of mine runs a company called corten miller who specialise in omex, or megasquirt simply for the price and additional functions such as launch control and boost control. boost cotnrollers cost over 150 for a decent one these days :-(

Sorry for going on.lol
