Here's the latest on the 576XP Autotune. Today Husqvarna said that production of 576XPs with Autotune didn't commence until 2/2009. Also, the word "Autotune" will appear right under 576XP on the saw label. If a dealer tells you he has the saw with Autotune and its manufacture date was before 2/2009, he's in error according to Husqvarna.
