I've been trying to update my SO6 with the newest software. Called Bob and he e-mailed me the instructions. I've gotten to Page 10 but that is where I get stuck. It won't EXTRACT the file. Let me back up a bit. I'm not sure that I have the right file to extract, the web site lists the orginal to update is the 4. 16 version & mine is the 4. 06 version. can I still do this update or do I need to get the . 10 diffrence first. The update process is not as eazy as it says it is. The instructions are NOT very clear for those who only know enough to get in trouble. If someone has done this could you PLEASE help. I've recently installed DDP injectors and an aftermarket turbo. And I need to control the SMOKE! That poor Mustange GT got a window full of diesel smoke on Thursday. If that was you I am sorry!
