I guess I didn't get post #47 out quick enough, it seems that I have rubbed you the wrong way.
To ansewer your question though, no sir I have not. My car has not even been to a track, I have very limited spare time and live in the middle of nowhere. I have tried this year two times, but both events were cancelled because of weather. The only thing I have to gauge what my car will do is a new model RR-G-tech meter.
