Hooked it up today and took it for a quick ride. Im very happy with it,my warrior is different quad now.I can ride a wheelie in first and shift to second now. I weight 210, before I could only do first gear wheelies. I got a one year warranty from Dyna and a dyno sheet that shows the power curves( post a pic of it when i get a chance). Curve 1 looks like its for bottom end( did not try it), curve 2 for all around power ( going to use this the most and I have rev limiter now) and curve 3 for top end, tried it as soon as I hooked up( won't use this because I only have a stage 1 hotcam and I don't want to float the valves or cause any damage, dosen't seem like there is a rev limiter for curve 3). You also have to change the jetting for it. Wish I bought this sooner, don't know why a lot people don't have it, besides the cost(only paided 150 for mine on ebay).
