you sure your wideband is calibrated correctly and there is no leak in the exhaust system before the sensor? if your afr is really 15.0 at WOT then your car probably would not be in one piece right now

My evo or running way too rich but that is because the fuel quality here in china is very bad. At idle I am running around 13.7 and at half throttle I am around 12 and when at wot I am around 10.3 which is quite on the rich side... Guess my tuner is playing overly safe from what I read over in these forums.... I have a BC 2.3 stroker, FP black turbo running 1.8 bar boost.... How much more power would I get by running my fuel leaned for example wot 10.3 to make it like 10.9-11.1 ???

I think this was a troll post lol. If not, then i think u should run a bit leaner, see if you can break the 'leanest before it blows' record
