So, I see that some of the community have welded an O2 bung into the crossover pipe to avoid the interference issues. I'm planning to do this for my next install on an 03 GTP. Are there any practical fueling related issues with regards to only reading exhaust off of one bank?

I realized that this is only for closed-loop cruising, not WOT, but I don't want to goof the fuel economy on my daily driver.


Alternatively, does anyone have another suggestion for placement? I've read that distance from the head can be critical.
