It didn't really seem like it made a difference between running Sport 3 and just being in Drive when at full throttle the whole way. Passes 1 and 3 were in Sport 3, and the 2nd pass was just in Drive, and it landed right between the two passes in S3 for both ET and trap speed. That could just be a coincidence, but yeah, I didn't feel a noticeable difference. The big difference was really running out the gears longer in manual mode and taking more than a 10th off the ET.
