Each engine will have its little quirks, speek with the top guys at your local track who run the same engine as you. Get them to tune it but ask what you need to look for & what they have done to achieve this tune, as this information is priceless. You will now have a good start point & are now at your first stage of learning to tune your own engine. The explanations in the forums & bible are a great guide but hands on cant be beat.
