Hello Mfavor,
During the ending cycle of my Break-In Process I usually try to feel if there is still a "Mechanical Pinch" while it's Hot or not. If I could feel there is still a pinch then I will not lean it to Racing Tune. Patiently run the engine again at about 80% until it "Loosen Up" at close to maximum operating temperature..
Cheers..
