Your kidding me, right?
That's like asking a company who makes swimsuits, if they'll make them fireproof because someone decided to pour gasoline on themselves and light it on fire.
Ford's Mustang out-of-the-box works perfectly fine with the stock DS. If you are going to go around 'upgrading' or making 'changes' to the vehicle, then its up to your discretion as to what you want to do with the car. Not Fords.
But the swimsut company doesn't sell the gasoline.
