In TSB Z-14-01 for the new helix, it mentions that there could be a performance decrease if installed in a 2 seat XP-1000. Has anyone that has the new helix in their XP4-1000 experienced any performance decrease? Is there any downside (other than having to arm wrestle my dealer) to getting the new helix installed? Sorry if this has been answered before, but I can't seem to find it in the hundreds of helix related posts.
Thanks!
Thanks!
