Nice numbers. It's hard to read those charts because of how they scaled them, but those are very healthy torque numbers for the mods you have and the fuel you are running. Maybe a little too healthy. What correction factor was the dyno operator running? Anyway congrats on your numbers and taking the time to dyno.

When you dyno an AT, you put it in manual mode and hold it in 4th to red line. Even in manual mode, once it bounces off the rev limiter, it changes gears automatically. That does weird things to the dyno plot and fuel/air metering, so you have to either lower the test window RPM cutoff on the dyno or just disregard the very top of your curves.
