Did you go with their dune set-up? Are you running with or without paddles? Where did you feel the biggest change from stock was? I heard you will lose a little top end with the duner set-up, which is fine since I don't think that I've hit the 70mph range yet.Im very happy with the EPI setup . Made my Commander come to life Very fun to drive now . All 3 of my friends are getting this kit . It still has a little noise on first take off but much better over all .I have around 400 mile on the belt .
