I just can't decide if I want to spend the money on this or not. I have a 2007 4.7l. Is this device specific to my vehicle? Can I use it on my 1996 Cherokee Sport 4.0l? I would like to turn off the TPMS on my Commander. Will this device be useless if I sell my COmmander? (heaven forbid that should happen). Who is using it on their 4.7 and do you think It's worth the cash? What else will it do that might tempt me to buy it?
If I were to use the 91 octane setting do I have to run 91-93 octane in my tank or can I still use 87 octane? I've never even heard of such a device until a few days ago so I'm basically in the dark as to it's capabilities. I picture me bricking my Jeep by changing a setting and then it won't start. Could this happen?
