I just got the XX back from the tuner after having the big 3 installed. I went with the full barker exhaust system including the "custom" lid, K&N Air Filter and the Power Commander. The best dyno run had her @ 42.66 HP and 39.82 Max Torque. I thought the numbers would be a little better but am guessing that being at 4400 feet above sea level isn't helping. That being said what a huge difference!!!:hey: Won't repeat everything everyone has stated about the big 3...all I can say is it is true....go buy it!! Just thought you guys and gals may be interested in the numbers I got off the dyno.
