I'm kinda glad they don't do it that way...... if they did, everyone and his dog would be trying to make their car run "great" and end up destroying the crap out of it or defeating emissions or just making it run like crap in general. If it came that way from the factory then there would be so many lawsuits that they would prevent people from trying to tune them again like that. Hooray for stupidity.
BTW megasquirt is awesome and costs near as much. THAT is a ton of tuning from your laptop http://www.diyautotune.com/catalog/d...kit-p-421.html
Aren't they unlocked when they are "unmarried" from the vehicle the tune is installed on? I know it's no good that way because it was traded in though.
