It is not a good idea to use the amount of turns in on the HSN to judge a "good tune". I have gone through about five traxxas 3.3's and have gotten a good judge of how much I should turn the HSN in to get my tune, but still its a bit different for every motor and different climates, break in etc. Some may disagree, but I advice getting a temp gun till you learn how to tune by smoke/sound/performance. These nitro motors run best between a certain "window of temps". Id say around 220-260 would be a good place to be.
