AEM UEGO? single or dual?

so i just bought a new OEM Coil pack and now the last thing i need to buy to properly use my AEM EMSv2 is an AEM UEGO O2 sensor but am a little lost

i have been reading about them and see that people seem to run only one o2 sensor, but then i see a few people that have dual channel AEM UEGO's and are running 2 o2 sensors.

so what should i be running 2(since stock runs 2) or do i only really need 1 AEM UEGO o2 sensor?

this is for a 92 VR4 Stock + AEM EMSv2, AEM MAP, AEM IAT,

any help or links to info about the Pro's or Con's of 2 vs 1 would be greatly appreciated
thanks

It's up to you. Im running only one o2 at the moment. You can use two if you want. One for the front bank and another for the rear bank. If you run 2 you can tune them independently for more control.

Single is fine. Install it after both banks merge.

if you're really concerned, install both and monitor them. if they pretty much stay in sync, switch one to the downpipe and sell the other.
