2020 here. Running Cobb stage 1 for now, with TCM tune. The original transmission tuning with skip shifting on regular settings was awful, and hanging on to gears too long in sport. TCM on OEM+ was actually not very good, and I was concerned that Sport would be too much. Now running Sport mode and it is actually smoother than OEM+, and there is no skip shifting. MPG has dropped 1-2 miles with a good mix of highway/street even though I feel that I'm driving about the same.
