    Does the new engine "flash" change the engine's attitude and performance? I love the rumble of unburned fuel when you do a high rpm downshift on de-accelerations. Plus it sounds a little bit like a "big cam" car when you start it up in the morning.

    I'm thinking about not having my ECU flashed unless there is a "safety" issue involved. You know...why fix it if its not broken....

    My ECU flash did not change any sound in my car. I still have that gargle sound!! All is good!

    Took my car in and found out I needed both a PCM AND TCM re-flash. I also had the RRT done for the HK Amp. Not seeing any difference in performance....at least not any I can feel. My car was built in July, so I think this was probably the re-flash they did. I did experience the car stalling out 2 of 4 times whenever I tried to remote start it. Almost seemed like it would try to turn the engine and fire up before the fuel pump had a chance to fully pressurize the injectors. Hope this solves it.
