its only worth doin if you are goin with cossie or aftermarket management

mate of mine did it had a stage 2 erst making about 200bhp on mfi swapped to standard ofab efi and got standard car power fiesta turbo managment is very expensive to set up compared to mfi

like everyone said if you changing management you need the efi bits anyway

its a good mod but to get you car to even stage 1 on efi will cost you about £200 for a chip, £50 for a decent filter, and not sure about beige injectors about £200 again id imagen the a set up about £200
