I will tell you my 2015 Edge Sport I bought brand new in August 2015 was tuned at 10,000 miles. From 10-20,000 miles I beat the living shit out of it datalogging for my tune. Probably about 200 1/4 mile runs and 30-100 runs, 0-60 runs in a 4 week period. I’m now at 150,000 miles and thats 140,000 tuned miles. I have yet to have a single issue with the engine besides a bad alternator.
