remapped unlocked HDi ECU.. worth much?

[Jay]

just a quick question regarding the value of an ECU removed from a 110 2000 406 hdi

it will be unlocked and remapped just after x mas hopefully (maybe before) to my car... FMIC, de-cat, de-middle box, free flowing back-box and blanked off EGR valve

remapped by a well known lad in Doncaster, he is great when it comes to diesels, my car pulls well with just a light map on it, but i want more power, when i have blanked my EGR valve and fitted my exhaust with de-cat etc, i will be taking it for a bigger map, which is when i will be gwtting my spare ECU done at the same time(to the same power), also will be having it unlocked to go on any other car

any interest and values welcome..

thanks
