There are many answers to this question as they are leaving room for real world problems. Bad fuel, Hardware problems, Lower octane, People who don't maintain a engine correctly, warranty's. Not willing to spend much time tuning for peak hp. Different engine loads due to tire size change.
This is why you must run the designated octane per the tune or you risk detonation and popping the head gasket. everything in my tune is calculated for more HP and Reliability as long as you run the proper Octane. all the best
