It worked. Installed with no errors. Super easy just like your install @bluelodge400. Thanks @r33. I can feel the 507 HP and 564 tq now. Wow. No more throttle delay in eco pro or comfort mode. I didn't drive on the highway or anywhere fast, but briefly putting the car into Sport mode made the car want to go fast. I'll report back after I drive it more this week.
Here's pics of how it was installed for the RaceChip TB Ultimate for 5.0i: I obviously zip tied the wires and the chip securely. This was just how I plugged in initially. I did the driver's side first, then the passenger side and then plugged into the chip all while the car was off. Started it up, and zero errors.
