I have a 2014 Silverado l83, single turbo.
I am having a torque management issue that I have not been able to find anywhere else on the internet.
During part throttle shifts, 45% to 80% throttle, it will pull timing for the shift, then after the shift is complete it will pull timing again.
Here is the charts for the 50% throttle shifts. 50pct.JPG
In the bottom group, the white line that bumps up is timing advance. The blue line in the second group from the top is the shift time.
Under mid throttle the 1-2 shift is super long, and then for 2-3 and 3-4 you see the double timing advance.
And here is a 2-3 WOT shift, very fast with little timing pulled. WOT.JPG
Any ideas? The trans tune is stock. I have focused on VVE and VTT tuning to make improvements so far, but cant figure out this odd issue.
