Default Afr on 1100 turbo

I installed an aem adjustable fuel pressure regulator on my 1100 turbo I also have afr gauge and boost gauge my fuel regulator is set to 43 lbs key on and when under idle its about 37-38 lbs at 13.0 to 1 afr. I haven't had a chance to ride it yet question I have is what should I be looking for as far as afr from vacuum to 0 psi? And 0-5 psi and 5-10 psi? And so on ? I plan on trail riding and also some racing up to about 28 psi of boost on c-16 this winter . I know for wide open throttle I should be about 12.8 to 1 but just not sure on the in between . I have turbo dynamics tune eco-max 94 and race .

Thanks

cruise, 13's is fine.
WOT, low 11s, 11.2-11.4 being absolutely perfect

Yes like Tom said. Low 11's at WOT is perfect on pump gas. 12.8:1 is too lean on pump fuel for WOT.

I'd be more concerned with why your sled is so lean WOT, not if it can run that way. No tunes out there run that high AF, that I've ever seen.
I would look at your regulator and make sure it's working correctly under boost. I dont have a lot of faith in those, which is why i run stock regulators well into the mid 400s hp.

I've got a video of a 25psi practice run in a 1,000ft. 40lb fuel pressure on my fpr as a starting point than I work my way up on boost and fpr if needed. Anyway im very close to what your asking in this video. My gauges should explain the rest. Old can of c16 left overs from a radar run 2 years ago. But she still took it lol

I am curious as hell as to how anyone could tune a sled with out a FPR unless you use a vipec or some similar, fuel pressure reg FPR is so simple and is a must have for find tuning just my opinion.
