One of the biggest misconceptions is the heat mark being on the bend - I've seen engines that are over timed before the bend. Best way to tune is to look at your MPH at the track. Pull a degree, if it slows down, add it back +half a degree... once you no longer see an increase in MPH take it back down. just go slow with 0.5 degrees at a time.
