I've never tried, but now I'm curious. Does HPTuners just prevent it or can it not be done? I'd imagine that if your ECM dies, GM can assign a VIN to a new ECM. But at a minimum I bet that's a one-time thing, can't be rewritten.
I'd say it probably requires a fancy Tech 2 machine or something, but since HPTuners can do pretty much everything else, if they don't do it, it's either by choice or because it's impossible, I'd wager.
