While I haven't tried the XS tune (I run the 87) I have read in other threads on here that it's anything but a fuel saver. I believe the consensus is that the XS tune is junk. I have only had the 87 tune for a few hundred miles (I don't drive the Jeep daily) and have to say it's a huge improvement over stock. I may try the 93 next with 93 fuel. I'm in Maryland and our stations generally have all 3 grades of gas.

I like the 91 tune with 93 octance, damn ethanol in this humid state attracts too much moisture.
It would be sweet if they offered the premium fuel (91 octane and above) ethanol free.
i used to be able to get it and what a difference - better all around.
Next add-on, muffler and hopefully next year - HEMI
