If your we're on a different type of dyno you could measure AFR under load at steady speeds. Even up to 100 mph my 1150 has gone into Closed Loop which means the AFR will be set by the transition point of your O2 sensor which is 14.7:1 in your case.
They knew what I was looking for. Not just peak numbers, but overall conditions. Since this time of year is slow, we spent a decent amount of time in the roller. Luckily, since it is slow season, it only cost me what the tech cost the shop; $30.
We ran at those cruising speeds for a couple minutes. 40-80mph in 4th 5th and 6th gear. Until it started showing 5 bars on the temp gauge, and then we let her cool down. WOT runs weren't much different but maybe by a couple tics. We did not do any cruise under 3k rpm.
