You said "Lambda curve is starting to drop"?

Are you reading off the stock Narrowband sensor?
If so, that is fairly normal, as on the rich side of stoich the NBO2 sensor output is much more dependent on sensor temp than on AFR. The output voltage (for constant AFR) drops as the sensor gets hotter. IF you are reading a NBO2 you might just have gotten the sensor warm with some hard driving.
