I tried the zero point calibration and saw no results (used the paperclip method). I called my service adviser, and she said she would do it for free for me since my Tech Stream won't be in for a while. I am just thinking of letting them do it in case I didn't do it right. I am having the 488s and Auburn LSD installed Friday and think that is what is going to make a difference. Wonder if I should even worry about having them do it?
