no... as I mentioned, there is no need to restore the backup first...

just hook the predator up and go to install a tune just like you did the first time... except instead of choosing "Install Tune", select "Modify Tune"... after making your adjustments, click the ESC button a couple times, it'll ask you "Install tune now?" - select YES and away you go! it installs the tune with your adjustments in it...

B,

To answer your question about what octane the performance tune is for your truck, it is a 93. But around here in MN we don't have much choice on getting 93. I have been running 92 for months without any problems. However, your 6.0L could be differant. Just monitor your knocks when you run 92. If you have any, retard the timming a bit for the 92.
