Dream2000 -

Yes you are right. I can create a file, and I did the same as you and made the test file I believe it was. After I could not get it to work I deleted it. I guess I could shorten my .ctd files but I like keeping the names the same as the .tun file so I know what one matches what .tun file. I have multiple tunes for multiple trucks so I don't want to get anything mixed up.

As far as performing a BBF I don't think you will have a issue. I just flashed one of my trucks today back to a different tune and it worked great. I sure do like changing tunes with the V2 its simple and fast. I am going to put a DSP5 on one so I can change tunes with that.
