Last weekend, while driving my 2013 3.0 TDI on a long highway trip, I noticed some delays and sluggishness during gear shifts that got me wondering if transmission tuning could help. Has anyone with 2011-2016 models experienced improvements after modifying their transmission behavior? I'm specifically curious about whether these changes really make the shifts quicker and smoother, or if the difference is mostly subtle. Also, I wonder how much impact a transmission tune has on overall torque handling and the vehicle’s responsiveness in everyday driving situations. For those who tried it, did it change the way your 3.0 TDI feels during stop-and-go traffic vs highway cruising? Any insights or advice would be appreciated since I’m weighing if it’s worth investing the time and money.
