I went to Torq Speedlab this morning (video is uploading now) for a new baseline on Roxy. The graph is raw data. SAE correction factor was 1.03. The pull was done on a Mustang Dyno (eddy current type add 30 HP correction). I've "done the math" and marked the sheet with corrected values.

A couple of friendly observations:
The graph indicates the numbers on the dyno are already corrected for SAE conditions (that's what "WC" means). You don't have to apply the factor again.
Where are you getting the 30 HP correction? A properly-calibrated Mustang dyno doesn't need to have arbitrary numbers added. The values are directly calculated from strain gauge data, and unless the strain gauge is out of calibration, there should never be a need to add arbitrary corrections. Mustang dynos should be calibrated ("zeroed") before every series of runs. In addition, these dynos need to be "zeroed" and "spanned" with a calibrated weight every few hours of operation.
Why are you translating numbers back to the flywheel? Unless you do a wheels-up coast-down test on the dyno your running on (and I don't recommend you do), the 20% figure is just a shot in the dark.
Instead of introducing a lot of random error to your numbers, stick with the same dyno, and stop trying to build the numbers up to some "ideal" value. You'll never be able to figure out true gains if you do; you'll just keep chasing after numbers.
You're running extremely rich. You should be in high 11's/low 12's. You're leaving a lot of power "on the table" running that rich.
