I have a question on best placement for 02 sensors. I have the kbracing log manifold (im pretty sure) so I have my stock drivers side manifold with the 02 sensor there. I have my wideband in the lower cross over. I have a spot in my down pipe or a spot right before the turbo in the merge part of the log manifold. So should I leave the wideband where it is? and should the narrow band go before or after the turbo?

 

Narrowband can be before on the correct side. Wideband needs to be after the turbo in the downpipe.

 

alright, I will do some swapping around. I was fighting some issues and ended I needed to swap to a 2 bar tune I was getting bad readings on from my MAF it is now removed and I was trying to do it all correct. I moved them all over thinking that was my issue. I will put them back and get this going.
