Out of the box this stick gave me a good positive vibe. I hooked this stick up with my 2013 Rome 390 Bosses. I haven't ridden on the mountain yet but I have played around with a kicker i made in my front yard. This stick pops hard. I LOVE it! I cant wait to put it through its real test. I am very pleased. Thanks Dogfunk for the sick offer, you guys are my number one online store to hit up. Keep it up!
