“Hey Mark, just wanted to drop you a note on my car. You tuned it for me while I was down there on vacation in late October. The car really ran smooth and we got 20 mpg going home. That was a sight better than the 14 mpg going down there. I am still pursuing on getting the O2 sensors turned on if I can have the short diagnosed. I will let you know how it comes out if I ever get it resolved.  THANKS for your help.”
