Hi,

Try an after market management.

Don't forget that Fiesta and Sozy Management is over 10 years old......Think what computers were like 10 years ago.

Management has become so much more accurate since then.

Try www.DTAFast.co.uk
They do some real top spec ECU's that have Traction Control, Launch Control, Turbo Anti Lag.

You will find that they can work out cheaper in the long run as well.
ECU's cost around £600
Wiring around £300
Full Mapping around £400
Total £1300.

You could easily pay £2000 for a decent Cozy Management install
