VERY High AFRs, but running very rich.

So the Hondata ECU is thinking that the car is running VERY lean at idle / low boost numbers. Once I get on the throttle and build boost, the AFRs go to much more normal values.
The car when getting these high AFRs (20+) is actually running very rich. I think the issue is that I had to put the wideband before the turbo wastegate so when at idle there is vacuum behind the wastegate dump and not enough air flow through
I don't think I can move the wideband because then it would be AFTER the wastegate dump (and that could mess up the numbers too). Thoughts?
