I call BS. Evidence? Maybe, maybe in a straight line. But certainly not around a road-course.the new Mustangs are actually faster with an auto.
Also, I had every single spec on my SE minus the winter package--it was still 3.5k less expensive all told than an ST. So the entire 'ST is the same price' argument is kind of out the door here.
We're straying from the point, anyhow. SCT, or someone, needs to make a tuning device for this car. People have said the existing XCal will read the Focus' codes, so it's not a matter of technology. I don't care who it is so long as they're reputable and have results. They will have my money.
