Where to place wideband sensor on twin turbo
#2
i have twins on my 5.3 and put the wideband aproximately 2 ft after the turbo, i put mine on the passenger side turbo(not that it matters a ton) ive heard that running it before the turbo in the hotside pipe will shorten the widebands life due to extreme heat, it seems to be working good for me so far. make sure to mount the wideband as to position the end of the tip at a downward angle, this will help any moisture run out of the sensor when it sits and help stop corrosion, just my 2 cents.

I also positioned mine on the passenger side downpipe only. It is also about 2ft past the turbo and just after it starts to bend downwards. Same reason so it won't sit in any condensation. Worked like a charm so far. Only been a year but it is my daily driver.
