Same with other gears, 3rd gear can be the difference between pulling hard, and pulling so-so.
Going to look into the ATR, not overly familiar with any of that. Links appreciated if you know them off the top of your head. Off to the search button, thanks!
You could be experiencing the feel of the throttle closures. I know when my were bad it felt like a heavy hesitation. Check the graphs and logs around that rpm and see if that's where.the throttle closures are happening.
