Mimi,

Maybe that's not all grin! Cumulative effects from acceleration over time may be causing it.

Ed,

Through MARCH (today), cost for remote tune is $265. They'll send a cable to connect the car to a laptop, and if you make changes to the car, retunes are free.

I've seen 15-25 HP gains mentioned here. I didn't even ask, because the comments on the Forum are so positive. Some do have dyno results to substantiate. In perspective, that much horsepower would probably have cost more forty years ago, when gas was 40 cents a gallon and I made a dollar an hour.

It was easy, and I'm no computer wazoo.
