I have an UpRev tune currently on my Infiniti M56S. My dealer says that there is a TCM and ECU update that needs to be performed on my car which improves shift response, behavior, throttle response, etc. But I told them not to do anything yet, because I have an ECU tune currently active.

Now, after I flash the ECU to stock and have the dealer perform all the updates, will re-uploading the tune into the ECU override the new software updates?
