it's like changing the firmware of your mobile phone, the program is change and the data are same than before ....

I am sure that Stu can do that because i know who had wrote the program ...

but it will be expensive, you will pay for the transfer work from one chip to another and you will pay for the little board under the chip which will crypt it...

and after, your original tuner will not be able to change something on your chip ....
