No.. the original owner can un-marry it and then you only have to pay $250. for tunes.
I have an SCT Tuner that I bought from Torrie. I decided I wanted Livernois tunes for it, so they sold me their tune package for $250. However, they are only 2 bar tunes. They wouldn't give me any tune support for methanol spray, or for 3 bar, without me coming in and having them dyno my Flex. This is not an unrealistic request, as they don't someone blowing up or otherwise damage their vehicle on their tunes, without seeing what they are tuning.
I hardly used the Livernois tunes because I started working with Torrie using W/M and a 3 bar sensor. Torrie has one logging WOT runs and sending him the logs, which he then uses to modify one's tune. That's how I became the first Flex in the 12's in Oct 11. Torrie is great to work with!
