GEN 5 TORQUE TUNING:
2015 Silverado l83 6l80e OS 12664769
Has anyone had issues where you update the VT tables for airmass, then look at the map table and all of the values are negative numbers? One tune revision, it is fine. About every 3 times I?ll check after major drivability issues and the MAP virtual torque values all all completely negative. It has me scratching my head.
