Hey, 07 SHELBY!
I would love to get up there so we could ride around in it! I'd have to guess 11 hours to get to Detroit area.
I want to keep it under warranty, so won't go overboard with mods. I have the C&L cold air, Bassani x-pipes and Magnaflow axle-backs on my '05 GT along with the Hurst shifter, which I dearly love! That would amount to about the 1st stage Ford Racing Package I guess. But, the Whipple is a very attractive option, except that I know it will be expensive to buy, let alone have Ford install it in order to maintain the warranty.
Actually, I asked my sales manager guy if there would be a warranty extension offered and he didn't know yet. He told me that it was not available on the Ford GTs they had sold.
