Tuning Timing

• Adding timing will increase torque, with horsepower increasing along with it. As you advance timing power will increase, increase, plateau, then knock. You want to see quite a gain from a degree of timing, maybe up to 10hp per degree. On the street this becomes very difficult. If you’ve been adding timing and all of a sudden the car doesn’t “feel” any faster, take that map off of the car and reflash the last timing map onto the car. There is no point in adding more timing than you need.
