V6 single turbo wideband location

Hi guys.

I have a KV8 which has 2 wideband controllers. Do you think I’m better off putting an ADV sensor on each bank pre turbo or just use a 4.9 and put it in the usual downstream of turbo location?

Thanks

I would say go downstream unless you can apply a corrective factor for manifold pressure in the exhaust. As well, you would want to prioritize measurement capability, but if location is important to you, it will work ehhh pre-turbo.
