I was giving the sled a royal cleaning today under the hood and noticed somthing about my helix. You can clearly see the marks that the nylon rollers make on it and they didn't go all the way to the bottom. The marks from the rollers only go about 3/4 of the way onto the helix so it looks like i'm not getting my full shift out. The sled is 2006 F6 EFI, it isn't a sno-pro but has the 1 3/8 track. I currently max out at 96 MPH but I KNOW it has more in it. Any suggestions?
