My firiend Peter, who financed the STS company, and who uses STS turbos on a couple of his racecars told me that the thing he liked least about the system was that changes in weather were constantly requiring a different tune. He said his crew had to keep modifiying his M3's computer to get it to run right in climates that it was not originally set up in.

If the weather changes much where you are, and you drive your car frequently, I would stay away from an STS turbo. That's just what I hear anyway, but I don't take his experience lightly, that's for sure.
