Do I need to manually update VIN numbers within the tune? coming from HPTuners it would let me flash a tune with another vin on it but it would autoupdate the file for me while flashing.
I've got a buddy that had his OFT stolen after putting an e85 tune in his car. I've got the current oft tunes and romraider setup to where it will read them but i'm unsure as to how i need to go about flashing something back into his car. I'm just trying to get him back on a safe gasoline map.

You can do this with the tactrix. You don't need to do anything with VIN numbers. In your shoes I would do the following:
1. Use the tactrix to read the current tune
2. Use a hex editor to find the string "ZA1J" which should appear three times in the .bin. The four letters/numbers that come after it are the cal ID. All three should match
3. First post in this thread should have some stock tune files for most known cal IDs. You can use the tactrix to safely flash one that matches the cal ID you saw in step 2.
