I figured about the rear cats, I might try defoulers because I was going to gut them. As far as the car its great. I wanted to thank everyone for the help. Ala, my Foxwell510 came today, you had mentioned you use it on your cars so I may check it out. I always have cars to mess with and it seems my Launch CRP123 is not so good on the older stuff. It was great on the XF, maybe I will sell em all and keep the PRO because you feel like a PRO with it!
