fuel trims are supposed to be 0 during wot. I don't know what tuner the poster is using, but with HP Tuners, it takes a few minutes for the fuel trims to relearn.

also, personally, I would not be driving the car with a ltft of 16.4, and would especially not be going full throttle. you could have an exhaust leak as well.
