PC5 and auto tune

You need a pretty strong base map to make it work right.
You mount the 02 sensor in the pipe, close to the silencer.
It works OK with a good base map, but you still have to fine tune it after the autotune makes its recommendations.

What turbo kit are you using?
If non turbo, you can mount the 02 about 3 inches toward the engine from the muffler joint area.
The autotune does not adjust AFR. You set up an AFR table and then the autotune makes recommendations to achieve that AFR. So if you put 13:1 in a cell and you are running 12:1, the autotune would say that you need 4 points of fuel taken out of that cell to get to the 13:1 you asked for. So if your value in that cell was 12, you would run 8 in there instead to get to that AFR.
Ulmers has some good maps and should be a great starting point.
