Hi,

Recently I saw someone that has 3 software on his car.
It's a golf 1.9 TDI 115 hp stock which does 140 hp or 240 hp or 265 hp, just by pressing a button can select next software. Make it because internal parts of engine are stock and for daily use 265 hp is too much.

Someone know how can do this either with only two variants?

Thanks!
