My car is currently at a garage who specialises in fiats, Its getting a new steering rack. I was speaking to him about remaps and he said his mate sells a plug in box which works well and is not the usual rubbish, He said they take the chassis number and a few other things and set it for the car. He said he can get it and fit it for £350, Im not too sure on figures yet hes going to get all the info then let me know (Tomorrow probably). Thing is though this seems quite epensive and its not really a remap is it. Anyone used these, Ive seen the ones on ebay for £100ish but he reckons its better.
