I am installing the holley dominator and have two o2 sensors and a front mounted turbo with a cross over from drivers manifold under the motor up to the passager log manifold with t4 flange for the turbo. Right now i have been running in open loop hp tuners and never had o2 sensors just a wideband about 20'' on the downpipe. i dont have a place to install on the passanger side pre turbo but can on the drivers pre turbo if i need or just place on where my current wideband is now.

Thanks

The question is??

Looking for the best spot to install the sensors. Do I need to install them in the manifold before the turbo or just install one on the down pipe? I dont use the with my hp tuner so the sensor location is new to me.
