Need help setting up my WUR

Hi guys from what I understand I
I first set my cold and warm pressure then set the co or afr to 3 or 13.38 with o2 disconected here are my questions

1-should I disconect the o2 sensor
When setting cruse afr?
2-What is considered cruse ,5th gear at 65 mph?and what to aim for? And I adjust the warm pressure to get where I need it to be
3-i set my rpm swith to 3900 rpm I have a k27 hybrid / bob exhaust and andial I/C and wastegate set at 1 bar
I now go full throttle in what gear ?

You set cold cp, warm, cp, then boost cp, double back and check everything.

I eliminated the narrowband O2 sensor when I installed headers. The emission system is very primitive and I felt that my car ran better in open loop.

If you have the O2 sensor connected it will set you to 14.7/1 at cruise anyway.
Otherwise, if you are using longer duration cams then stock and you ditch the O2 sensor, a little richer is good but I mean 14.0/1.

Sounds like you have a 5 speed transmission, correct? If so I'd recommend that you do your data gathering pull in 3rd gear so you actually get some load on the engine.
