Howto tell if Ihave a tune
I bout my 2003 ford focus svt used at the begging of this year feb-2009. I have taken it up to 150 mph befor and the governor did not turn on, some people told me that I might already have a tune, and some people say that the governor is turned off, but if I had a tune people say that my check engine light would not turn on when I have a problem, and it has befor with a o2 sensor code. My question is how can I tell if I already have a tune if there is a way? Please help because if I already have one I dont want to buy a new one, and Im looking into getting one if I dont.
