Just had this flash done today! I can definitely tell the difference. The SA said though that it takes a couple weeks (under "average" driving and start/stop cycles) to have all the systems re-adjust, so that leaves me with the question..

If you've had this done on your 5.0i, what did you notice in the first couple weeks, and how would you compare the first day with how it was after a couple weeks?
