Yeah, it does give you a good baseline for your sled. Even if you have the same mods as someone else, every sled is different with air, elevation and other variables. Then you can modify that map if you like.
What sled are you looking at a PCV and auto tune for? I have a brand new auto tune and barely used PCV with all software and parts it came with (including the box) for a low price. It was for the D8. Let me know if you are interested.
