IMO, if the leakdown is set pretty close, i wouldn't worry about the idle EGT, i would go instead to the full throttle run and keep the EGT in the neighborhood of 1200 degrees with the jetting/return pill. that's the way i do it, and most of the people i know who run injection. some cars run better with a little higher than 1200 degrees, some run better with a little less. Obviously the higher egt reading the leaner running engine, and actually better in most cases.
