You cant borrow tuners, once they are put in the tuner is set for that car the whole thing is either put in or it isn't you can't just install one thing and leave the rest in the tuner it is installed in one whole package. If you change a setting and then put back the stock tune the setting that you set is no longer there it is put back to stock, and once the tune is installed into a car you can not take the handheld device and try to intall it into another car.
