Well this turned into a shit show.   
For the record-I don’t have, never have, and hopefully never will have a personal problem with David.  He is abrasive, yes, but he is a straight up guy.  My input was biased previous conversations with those involved, and observation of the lack of any Switzer involvement in Dave's event.  Nothing more.  I was told something up front, saw not one Switzer car there, local or otherwise, got the cold shoulder from Dave, and put 2 and 2 together.  I can only work with what I see, and I have the right to my opinion.  It’s shitty Tym and David still seem to have issues 10 or so years since he left BR.   
David I am sure will build many potent GTR's in the future.  At this point, it’s a bit of a saturated market tuner wise, so I do wish him the best of luck.
