I would down shift in manual mode, hold 5th gear, and make a pull just through that gear. That is how I tune fueling. I was making 3rd gear pulls from 40 in the C7Z M7 to dial in the MAF so there is no wheel spin. The log I posted above was an example of why you can't tune off of lower gears...it was a final pull not used to tune.
