Bottom line is that the upgrades to the 8,600 RPM tune and a smaller pulley were worth only 5-10 HP and probably aren't worth it to most since it voids the ESS warranty. I like the flexibility of the tune and typically try to shift around 8,300 to 8,400 RPM at the roll-on events which gives me some room for error to prevent hitting fuel-cut off which completely botches any acceleration run. Another reason for keeping the revs at 8,400 is that it starts getting a little lean at the very top which means I'm running at the limit of the fueling capacity.
