Hi...Yes, the TCM tune makes a huge difference with shifting. Should have had those shift strategies from factory! The ECU tunes make a very marked difference in performance as well...And I had a custom Goosetuned set for mine with 93 Octane and Water Methanol Injection. It was very fast and ran great!. I never really checked the gas mileage.
