A buddy of mine let me borrow his wideband. I had some problems getting my AFR leaned out for a bit and started another thread to get some help.
https://ls1tech.com/forums/pcm-diagnostics-tuning/498799-i-can-t-seem-lean-her-out.html

As usual, several people in the know stepped up and gave me some pointers which allowed me to get it worked out. My AFR is right at about 12.8:1 or so. I am now ready to strap up and put down some aggressive numbers. I hope to get that done very shortly but I feel very confident about it.

I have thrown a couple of codes with regards to voltage or something.

Could I take the TB off my 04 GTO and just swap it using the sensor in the newer one? Is it compatible mechanically (I know that it is) and electronically ?
We had this problem with a friend's LS2 402. Turned out to be running on 4 cyl. Our issue was a fuse for the injectors. Car pulled 475 through a built A4 w/ stall.
