It's all about control not money they want a factory tune that is safe. They will then be able to void your warranty if they can prove you used a non factory tune.

I think most would buy the FP tune since it would retain the factory warranty.
$$$$$
What would the cost (approx.) for a FP tune? I've never purchased a tune so I don't really know.
Probably similar to the Mustang stuff...
