Run one wideband sensor?

Almost done building my hotside and was thinking about 02 placement. Heard to just run one wideband down stream post turbo and heard to run 2 pre turbo.

Im running all Holley stuff, LS2 harness and Dominator. I see just one wideband connection on the harness, better to see what both sides are doing tho?

You jumped in the deep end of the pool. The wideband will get your tune close but now you need to look at plug readings.

A wideband is always downstream of the turbo. Pre turbo and the back pressure will skew the readings.

Also the high temperature of pre-turbine exhaust is too high for typical in-car wideband sensors. I have one in my downpipe approx 5' from the turbo, its down by the trans.

Colder is better. Dyno wideband works great from the tailpipe, doesn't it. Just make sure you have NO EXHAUST LEAKS.
