im unsure where to post this so im doing it here so bare with me. ok im going to be running true duals on my trans am and ive deleted the computer completely. my question has to do with me adding a air fuel gauge to help monitor the motor a lil better and aid in tuning. DO i need to use two o2 sensors(i would think so) and where would i have to mount them? please help.

2 would be better than 1. 8 would be better still, but probably a bit overkill in the real world.

If you did 2, you'd probably want them in the collector right after the primaries come together. As close to the motor as you could realistically get them, and still read all the cyls in question.

not to sound stupid but id run both to one gauge correct? im not very good at automotive computers adn wiring in general so bare with me
