Looks like quite a few Texas cars have taken the "fastest" titles over the last few years - we do Japanese better than even the Japanese do it
And with regard to aftermarket tuner warrantees, many are stout in word but weak in application.
Too much leeway for the warrantee provider to use the "you raced it" denial.
I would think if youjust spent $50,000 upgrading a car you just paid $120,000 to get early, the $20,000 repair bill of a broken tranny is something you accept you will have to cover.
