Timing drop in 5th

[bytor]

2008 Saturn Sky Redline LNF/Auto. Smoothing out a tune and happy with everything except what appears to be a timing drop when the auto tanny shifts into 5th gear. All other shifting events are fine, just 5th acts up at lower RPM's 2,300-2,600. (circled in yellow) Any ideas on how to attack it?

is ac on?

AC on or off didn't change things. I got it cleaned up using some of Codename Bil Doe's tune concepts focusing on timing, torque and airflow adjustments.

Throughout this exercise, I noticed a quirk in HP tuners.
There is a PID for current gear that shows up in the VCM scanner channels config window but it seems you cant create a graph or chart using this channel.. Odd..
It would be nice to graph the current gear to see gear changes relative to all the other data.
