I sent asked support this but maybe the Aussi boys are sleeping because of time zone differences.

I have a 2005 Silverado. Will it eat both licenses to tune the engine and transmission? Or does that apply to vehicles that use seperate PCM and TCMs'?

I have a Vista 32bit laptop and a Vista 64bit desktop. Can I install the same licensed copy on both?
If so can I work a file on the desktop and then move the file to the laptop later and load it into the vehicle?

Thanks.
