Alright, Today I decided to try my RaceTune, so I loaded it up and it all ran fine. Later decided I wanted StreetTune back for now as I was having traction issues. Halfway through the process it came up with "Error 1034: Could not download, please return to stock if car does not start" I then tried returning to stock as said, and it also came up with the error in the returning to stock process, after the ENGINE process had loaded. "1034: Could not load" (May not be exact wording) Now the car runs really rough on start up and I'm afraid to move it. I realise I'm going to need to call SCT or Tunehouse, but I'm posting it up on here tonight in-case anyone has a fix before tomorrow! Thanks heaps! Tom EDIT: 2010 FG Xr6 Turbo Sedan in-case it's needed.
