I went with the Mopar calibration from the Dealer.

$140. Drives like stock and factory

I use the vLinker MC+ and bypass cables. Works well with JScan.

Do these adapters dont connect directly on the obd port under the dash?

37's.

The calibration from Mopar corrects the Speedo, Shift points, and ABS from what I have been told.

Drove the Jeep for 2 days without the Calibration, and IDK if it's just me but after the calibration the Jeep drove just like it was back on stock 35's

If you're going to spend that much money why didn't you spend it on something that provides more than just that one thing? E.g. a JScan or a Tazer.

When adjusting settings (tire size, TPMS, etc) you need to use the cables from the security gateway located under the driver side lower dash kick panel. OBD port can be used to read and clear codes.

I just installed the Tazer Lite. It will do what you need, plus other changes. I got the refurbished unit from ZAutomotive direct. Not an ODB plugin, as mentioned before. It's direct into the SGW plugs . Quick and easy install once you locate the plugs on your version of Jeep.

Do i leave the adapter plugged in or take it off after making changes? Im new to this and my first time

Unplug after making changes. Be sure to reconnect the security cables to the gateway.
