I suspect you are running rich, 11:1 AFR is 0.74 Lambda and widbands sensor acuracy at this AFR is some what vague

What turbo are you running? could the turbine be resticting the flow of the exhaust gasses? Isambard Kingdom Brunel said:

I have std. inlet valves (33 mm) and 31mm exhaust valves from vw 1.6 TD |
