Do not continue to run a track that is rateching! Tighten the track, even if you think it's tight, tighten it more. The more studs (slinging weight) you have the tighter it has to be!
I run mine tighter than most would ever imagine. I haven't hung a 20 lb weight on it lately, but I bet if I did It's be at like an inch to and inch and a quarter.
I run it tighter than the video that PEFI shows. I think they say 1/2" sag, mine is 3/8" sag measured. Any looser and it will ratchet on me over 100-105 MPH. You need the good billet adjusters as the factory cast ones are junk and will crack. The more power you are putting down and higher speed you run the tighter you will need it to be.
