Should I locate my wideband bung in location A or B on my downpipe? A is about 12" from the turbo exhaust wheel. This is a 2 piece TTA downpipe. The turbo piece is about 6" long.

When I called AEM and Innovative Motorsports the suggested 24" from Turbo

I was wondering if you put the Sensor 24" from the turbo 18" from the turbo, before cat, after cat, exhaust pipe etc. Would the AFR read the same? Mine is where the Cat is suppose to be and always wondered if it would be richer or leaner than the 24" location. Some dyno's tune at the exhaust pipe. hmmmm.
 
after the turbo is where its suppose to be as far as distance, I've heard anywhere from 12-24"

Shouldn't matter as long as there are NO leaks in your system.
