(x-post from B5 A4) Could DTC 16517 cause boost loss?

DTC 16517 - O2 Sensor Circ.,Bank1-Sensor1 Slow Response - intermittent

This is the O2 sensor before the cat, right?

Could this also be a MAF issue?

Anything that has to do with af ratio is going to cause a boost issue.

If the car makes less power it will then make less boost.

I'm beginning to think that phases of the moon will cause boost loss with DBW
