I would try contacting MAST, I would imagine they have a proprietary ECM software that would prohibit you from programming it with say HP Tuners or EFI Live.

No they don't. They just run OEM ecus. Find someone up there in Canada that does LS tuning and you will be good to go.

Note, if I've gotten any facts wrong in the above, just ignore any points I made with them
don't believe a thing you read about the next gen Camaro -- as history has proven time and time again:
