Just wondering how accurate the wide band is they use on the Dyno that has a tail pipe probe. I was on a Dyno jet, Somone told me the tail pipe reading isn't as accurate. Is this true??

 

i would imagine that it is very accurate!

 

The tailpipe sensor has an easier chance of getting fresh air. Could make you read lean. Plus it's after the cats which may mess it up even further.

I personally wouldn't want my dyno tuner using one. But, many tuners do use that style.

 

makes sense!

 

A tailpipe probe is not as accurate as you need for a good tune. A top-notch tuner will weld in a pre-cat bung to get the most accurate readings.

 

I personally do not care for the wideband in the tailpipe.

 

You did mine in the y-pipe

 

Bahhhh! Oops!

 

it also depends on how clean the filters are.
