wideband reliable w/ open dump during boost?

[quik4g63]

im currently running an aem wideband. it is positioned in my 3" downpipe about 10" downstream of the turbo.
NOW
while i am in boost, can i rely on the wideband readings while all my exhaust is going out my open dump tube?

just a thought
thanks.

Do you have a verry effecient dump tube? .

The only thing going out through there is the extra flow to keep your boost at a set psi.

Makes me wonder though, could it change the reading?

It shouldnt, there is nothing that can change the exhaust reading since its in the downpipe and not getting in any air from the outside.

While we are on the subject...

We have a Trailblazer SS. We are about to put AEM wideband on it, and were wondering, if put the sensor in just one of the exhaust pipes (only sensing half the cylinders) will it skew the readings?

You might run into issues because your AEM sensor is too close to the turbo and will get too hot. I believe AEM recommends that is at least 24" from a turbo.
