I posted this thread over on M5board since we have an active community in Dallas.
One of the members there, Darren Dallas, knows you and your tuner and would like to have a run with you (in a safe closed course of course).
See this thread:
I guess this is an opportunity to you to show all the doubters on this thread. He will contact you through your tuner. Better yet, please go post on the thread on the M5board. I will ask Darren to monitor / post on this thread....
