Good so far. I am running a stock tune. While the roller /weight combo doesn't quite have the same bottom end "snap" my Heelcickers did, they pull well, engage low and combined with the straight 45 helix I gained 2MPG. And they last. My heelclickers wore out in 600 miles, with no help from Randy of Supertorquer .
I am debating whether or not to go with a 240 quick spool tune next year. The sled in stock form pulls well and has been very reliable. I would defiantly go with the quietest muffler I could find as I have gotten to really like the "quietness" of the Winder. No earplugs needed...
