Vehicle came in on the base tune from Procharger and the customer wanted to optimize the setup moreover the base tune, as well as tweak the shift scheduling, and for us to look into a cylinder 8 misfire that seems to be common in these platforms.
Also, since writing to the TCM I've also had a CEL for TCM communication errors, "service stability" light, and permanent "U code" faults. Currently back to stock trans flash, but would still like to raise the shift points.
Thanks
