Just curious to see what kind of results you guys are having with the narrow bands pre-turbo. I'm working on a car right now where they read great, but once you bring it into boost a few times one of the sensors fail and I'll see split fuel trims. I am curious if this is just the sign of a complete failure on it's way or maybe it has to do with the narrow band placement. I'd like to get some input before we just replace the sensors.

I run 5th gen camaro manifolds, but placement is preturbo, I have zero problems as others do the same. What brand, age of sensors, etc?

where is the placement? Mine are right before the turbo and about 4" downstream from the last primary tube. Only issue I had was with leaded fuel and a rich tune.

These are located right after the truck manifolds, It may just be a sensor not responding well to the heat. Not sure on the brand, looking into Delco or NTK for a replacement.

i run narrow bands in or right after the manifolds on multiple cars without issue.
