Folks confuse the ability to make power at a given level with the ability to properly control all part throttle conditions below that level. Once you open the flap completely, you are accessing the ECU map's top row. Any changes you make to that row affect not only WOT, but also all part throttle opening points in which the flap is still completely open. That means that you have a sweet spot right around where the ECU was tuned to run and then overly lean and overly rich conditions above and below it. I've seen this while doing dyno pulls at various boost levels on ROM tuned cars that were brought to me for analysis.
