Progress:
So my local Silber dealer finally got ahold of them and they said they would reflash it for half price, and I told him he should get something for his time too (which is only fair) so it is going to cost me $300 to get it reflashed in his shop... I agreed to it since Silber has you over a barrel basically. Opinion warning (don't care if others agree or not, this is just my opinion): I still don't like it on principal, as to me, if the sled / ECU has been flashed for the Silber turbo with that VIN (which it has), it should be customer support to reflash in the situation where their flash gets accidentally overwritten during maintenance by a dealer, period, which is what they do for the original owner (from what I have heard). Otherwise the kit is useless and the sled is dead unless returned to stock. Anyway, knowing this additional info about used sleds with Silber turbo flashed ECUs already on them (and not just used turbo kits sold in a box without ECU, I get that), I am pretty sure I would NOT buy Silber again, new or used unless it was basically a giveaway. Not having a piggyback controller is nice in some ways but not worth it IMHO, I would look into a different maker such as Mtntk or Boondocker or someone else (depending on budget) for a new purchase.
BUT this time around I will pay (again) to play, lesson learned. Hopefully I can pass on info to others about Silber flash digital wrench caveats...
And when thinking back to when I brought it in to the dealer, with my handwritten list of what I wanted them to do (oil pump number, injector color, gear ratio if possible), I did tell the service writer that it had a custom flash in it and to not reflash... just do specifically what I asked for (the above list). I will follow up with the service manager and tell him how it turned out (so they can learn from mistakes made too) and see if he offers to do anything about it... Expecting nothing but hoping they will try to make it up in some way.
In the end I will be brapping... that's what counts... I will post an update then it is all up and running and I am grinning ear to ear.
