Thanks for the reply.I purchased a CDI box last year and noticed the biggest improvement when starting out, seems to have more grunt to it. I own 78 acres and one trail that starts in the creek and goes right up the mountain side. Thought I would really see what improvements I would get. So first round was without the cdi box from dynatek. Seem to take a little bit for it to wind up, definitely needed that extra grunt when starting up the side where I have one creek branched over into my trail, muddy as hell, but fun going up. I made it to the top seemed to bog down in a few spots on the rpm's.
Second round threw back in the cdi box, and felt the extra grunt again, laid into it all the way up, no issues. got to the top and actually built up enough speed to where it jumped the hump at the top. All in all I would say that it was worth it. But what i do need is a aftermarket filter system. The one on sidebysidesports.com is 404 bucks. Kinda stout I think especially when I only paid 176 bucks for my teryx system.
Anyone know where I can get a good deal on a K&N Filter system or UNI, or whatever? Still shopping for an exhaust system, the prowler is the wifes toy and she doesn't want it insanely loud like my LTZ400 with a alba full racing exhaust. She and they neighbors can hear me on the other side of the mountain..
