Tuning wot is simple, the car goes into open loop mode. This means it runs off of exactly what you program, so you just adjust until a/f ratio is where you like it and add timing until your knock sensor doesn't think its cool.
For closed loop mode(cruise, idle) you want to watch fuel trims and basically fallow what they tell you, if your fuel trim is adding 10% fuel somewhere its because your o2 tells the ecu its 10% leaner than it likes, so you at 10% fuel and go from there.
