.02 o2 value on logger full boost

[95_Talon_nt]

car pulls great 1, 2, and 3 gear. But when the coolant temp reaches 175 and above on my logger car builds full boost 16psi and doesnt go anywhere. Fells like no boost at all, and i get a .02reading on my logger for o2 value. I know the o2 sensor is working it jumps around values during normal driving non wot. But when I go wot it does the .02 value. Any ideas , bad o2 senor ?

If so what brand o2 sensors are you guys using. Someone tryed to sell me one at adavace for 76.00 bosh.

Thanks for looking, hope someone can help
