That's kind of what I'm asking. I had a street tune . then hopped up to see what the street tune looked like. I didn't datalog either.
Target a/f max at WOT is 13.0 on my ****** aem wideband mounted in the xpipe but registered as a 12.8 with the sniffer wideband in my tailpipe on the dyno

two tuners have told me it could mean its a gap in the maf tuning but since its so low in the rpm band in 4th that it really isnt bad.
any insight?

I am no expert, but there is definitely something wrong in that RPM range. Hopefully some of the more experienced tuners can chime in.
I assume you spent $50+ or so for the dyno time? If I were you, I would spend the $400 or so for a professional dyno tune if your budget allows.

I don't know - it sure is stupid lean at that spot (even though it is low in the RPM range). This is just me, but I probably wouldn't be doing any WOT pulls until that is figured out.
