I had a Focus T190 years back with an Ian Howell specced engine running a modest 360 bhp (engine specced for 500bhp) that was firstly mapped by Ahmed Bayjoo then mapped by Harvey Gibbs and its a very good ecu for the money in fact it’s better than most others for the same money, but listen to Mark Shead on here use whatever the mapper of your car suggests as he will get the best out of it then for you!
