I agree with your strategy if you ride mainly in that RPM range and below 60% throttle. I am a revver so I would say that most of my time is 60% throttle and above. In that throttle area and above the 7500 RPM range, the AutoTune is constantly adjusting. Now that I kind of skewed the PCV base map by doing the ECM update, I do hope to get a custom tune at some point. Until then, I am going to adjust the closed loop area manually until I get the check engine light to come again, then I will trim it back and leave it there until I can get the custom tune done.
