Just installed the Cyberdyne vac/boost guage with memory.

I'm running about 11 pds boost at wot with IAT's of about 120 degrees. Also have the meth working today for the first time and the AFR guage appears to be working properly since I got the O ring installed in the fuel regulator. At wot it reads about 10 or 11, idles at 15.

It still sometimes throws a 171 and/or 174 code at idle. That's lean... but at idle only.

The Vac is running about 13 around town.

Do these numbers seem reasonable?

 

beautiful! the radix for me really likes being over 11.5 at wot. I don't like 12:1 but anything in between 11.5 to 11.8 is good and safe to me. 10:1 is way too rich. lots of power on the table. keep in mind (as I am sure you know) all trucks like different things and work differently. It's all a case by case in "what works best for your truck". But for just ageneral question...your numbers look fine except a little rich at wot.
