A custom tune should get you more than 25 on the 5.0. There is conflicting info out there as to whether or not the dealer knows you had a tune on a car, assuming you put it back to stock before it went in. I know occasionally Ford corporate will get involved in a warranty and they do have the equipment to tell if a car had a tune on it. Lots of 6.0 diesels burned the pistons with an aggressive tune and Ford caught on real quick. Personally, unless you are planning on something stupid like 800hp I wouldn't hesitate to put tunes on the Lincoln. It will also let you change shift points and stiffness. If you really want to make big hp in the 5.0, you need cams and forced induction which then require their own custom tune.
I haven't paid attention to the newer generation mustangs, but there are some convertibles that have a stiffer chassis than the hard top from the factory. Either way that car should be fine with another 100-150 hp on the street as is. If it was going to be raced regularly it should have sub frame and chassis stiffeners, but it's not needed on a street cruiser, even with an occasional drag run. Your weak point is traction anyway. That's why AWD is becoming standard on the European super cars.
But, as I learned a long time ago, if you really want to go fast for cheap you need a bike. I haven't ridden mine since my accident but every single time I rode it I hit triple didgits. It gets there with no effort and back down to the speed limit before most people could think about it.
That is a HELL of a good idea, I have a K&N already, but stock intake, so this will be an easy boost
This
here som’bitch looks mean, looks like about 20hp/26tq, for about $400 from K&N
