JB1 tuning box on 2020 OPF Cupra
Recently purchased a JB1 box for use with my 2020 OPF equipped cupra. Does anyone here have a JB1 box fitted to their OPF car? I can't find anything regarding compatibility with these newer cars. Don't want to fit it if it's going to have compatibility issues and potentially damage the engine...- jack rush
