Hi,


I like a lot the last focus mk4 with the st line and 1.5 ecoboost

I just wanted to get some more hp and was thinking it's the same engine as the mk8 fiesta st


when I check remap with puma speed or other tuners, I discovered they offer less hp (190 hp) compared to the fiesta st
I can imagine the 2 engines are different


what are the differences ?
turbo ? camshaft ? others ?


I take a look on google and did not find any informations

thanks for your help
