And its impressive!! The nieghbor had the dealer install the speed kit and he got it home yesterday morning. I wandered over last night to check it out, and this thing wheelies like nothing now, and he says he can beat his brothers 454 AC 4x, so he's extremely happy. I'm a terrible judge of distance, but I'd say he pulled a good 4-5 quad lengths on my stock Blazer in around a 200ft drag. I have almost 100 more #'s on my fat-a$$ then he does, so that didn't help me either. My one complaint is its too loud for trail riding, but he's young and likes that stuff.

The kit definatley made a big improvement, and thanks to all who helped out with all my questions about modding the boss!!
