It took awhile to download, but we were done in about 2 1/2 hours, as promised. Then about 20 miles of driving in traffic. I tried many times to get the shudder going, but couldn't, and it seems to drive more smoothly. I'll see how it's doing for mpg when this tank of gas runs low. My S doesn't have a readout of mpg.
