I was on a biz trip and saw an ad on-line that the ECM can now be unlocked for $1000 and the tune is like another $900. You need to buy tune credits for like $399 and a programmer for another $399 or so. The total to get it done was around $2700. You send them your ECM and in 3-5 days you get it back. I'll try to find the ad I saw but it was from one of the companies Axe may have mentioned in the past.
