Your supposed to dyno in the gear closest to 1:1, that would be 4th with 1.14:1. Since I have a 2010 I had to dyno in just D. the numbers are close but still wrong. My dyno sheet shows it shifted into 4th at 85mph.
In 3rd I peaked at 253hp (5.4L) just before shifting. Just after shifting it was on a steep climb past 253 but hit 100mph and killed power.
It starts in 2nd, then climbs in 3rd, then hits 4th and dies at 100
