I've had mine for 8 years now, and I made some big changes this year to it. First outing at the track, I went off (full 360'd it, it was sweet) because I just wasn't expecting some of the results of those changes. It's always best to learn, and make incremental changes.

Good to keep other experiences in the back of your head so you know what to do if your own experience matches up, but ultimately you won't know what to look for if you don't baseline it. And keep in mind your baseline that you establish can change even day to day - temperatures, track conditions, what you ate that day, your mood, etc. An installed part can't fix that.
