[Power Hungry]

I guess any time you increase the power output of an engine, there's always the possibility of stressing marginal components to the point of damage. However, it has been our experience that properly tuned programmers and chips do not have any adverse effect on durability of service life of the drivetrain. We've had customers with tunes for over 100,000 miles with zero problems with their trucks.

As for Ford, most often their stance is to avoid performance products but that is simply a way to avoid warranty hassles. Quite often, dealerships will sell programmers, CAIs, and even supercharger kits and still support the factory warranty. It's just that they want to have control over what's being sold. Their want their piece of the pie, so to speak.

Hope this helps.
