Ok im trying to get my WOT shifts firm and read hptuners website till my eyes bled. Anyone here mess with the 6l80e using Tunercats or Efilive I raised my wot rpmthats fine and I lowered the 1-2 2-3 3-4 shift times down. A lot of different tables compares to a 4l60 file which I have no issues getting to shift hard at WOT.
