Time will tell if this is a temporary "glitch" or if maybe hooking it up cleared some bad setting or something.

Car runs smoother and no hard starts since. Its only been a couple days. Time will tell, but we have some hope now.

Sooooo..... maybe try getting the dealer to run a diagnostic? MAYBE try shutting down the computer (unplugging the battery) and hooking it back up again to reset it. Just a wild guess, but might be worth a shot. (no warranties expressed or implied)
Regardless of what the trip computer shows only the actual numbers will tell. My gauge always reads 1-2 mpg higher than my actual mpg. I've tested with a GPS too to be sure my trip computer has my mileage correct. It's spot on.
