Good questions. I've always followed this guy's approach using the "street" method. Fortunately we have plenty of county highways near the Mexico border. It's not inconsistent with the owner's supplement language either. The key is to warm up the engine first, then run it up hard, but let off and let the engine braking bring it right back down versus holding it constant at a high RPM.302 Hi Pro said:

Here's the break-in procedure from the supplement:
Your vehicle requires a break-in period.
Drive your new vehicle at least 100 mi (160 km) before performing extended wide open throttle maneuvers and at least 1,000 mi (1,600 km) before performance or competition conditions.
Note: Vary your speed frequently in order
to give the moving parts a chance to break
in.
So my plan is to break it in according to the mototune process, but stay consistent with the supplement. I want to put 1,000 miles on it before track use.
We have a good thread on planned track mods started here: https://trackmustangsonline.com/index.php?topic=10292.0
Also a good question on first oil change. I generally like to change it after that first 1,000 mile break-in period. I'll probably do that, but I'm also probably going to extend the number of track hours between changes more into the 8-12 hour range. Ford still calls for 3000-5000 under extreme use so I would be well within that.
When to expect the OIL CHANGE REQUIRED message
Interval Vehicle use and example
Normal
7,000–10,000 mi
(12,000–16,000 km)
Normal commuting with highway driving
Normal to moderate load
Flat to moderately hilly roads
No extended idling
Severe
5,000–7,000 mi
(8,000–11,999 km)
Moderate to heavy load
Mountainous conditions
Extended idling
Extended hot or cold operation
Extreme
3,000–5,000 mi
(4,800–7,999 km) Maximum load or track use
Extreme hot or cold operation
