Thanks for all the input. It is a US computer. It is a 2000 Contour SVT that is still the 2.5 L. I just want to get it up to speed for European road systems. I had a SHO last time I was in Germany and it did just fine. The SHO was supercharged though, that is why I was trying to see about doing something to the Contour. With all the bad talk about any other type of forced induction on the Contour I think the SF turbo is the only way to go.
