No, with the chair installed correctly the outfit will pull to the right slightly when off the power. However, there's no absolute 'correct' setting, every bike is different.
For example, because I carry heavy loads all the time in my toolbox/chair, I have lots more sidecar lead compared to most rigs. My chair wheel spindle is nearly 13" ahead of the rear wheel spindle. Most guides say start at around 9". My outfit handles fine with teles and clip-on handlebars.
