If you always putter around, it will think that is your driving style...smart little car... If you want performance, you need to do this reset...but, it doesn't always work the first time. So, if you do the reset, and it isn't as snappy as you like, try it again...then, drive it like you stole it for awhile to learn your new driving style... If you don't, she will return to where it was before. I used to think this was huey...until I tried it many years ago....NOW, I just drive it like I stole all the time....lol
