The stage two is like $2g's so a bit pricey, but they will match your warranty and BMW will acknowledge this tune and will still service your car hassle free.... Just saying.
is this true in fact? so if you lease a car and do this bmw will have no problems with it? im assuming if they are ok and it doesn't void warranty, it shouldn't even raise an issue with anything. if a motor blew because of this tune, you get a new motor for free no hassle? is this true?!!?
