Someone tell me I'd be crazy to not delete the FADA

[Chaser]

With the FADA delete, what's the protocol on using the spare tire? Am I understanding TSB 23-2174 correctly that AWD will always be engaged? Doesn't that contradict the current protocol on using a spare tire -- 'drive slowly until computer disengages AWD.'

I recently got a flat and put the spare on to drive a couple miles and the 4wd off message came on screen. So either the system is dumb and fooled or it actually disconnected. Also the graphic 4wd display doesn't always AWD just rear drive unless under hard acceleration.
