Legally, they can deny warranty coverage due to an aftermarket part or modification only if the aftermarket part or modification actually led to the breakdown. This is a provision of the Magnuson-Moss act. That doesn't mean that sometimes companies will try to use whatever they can as an excuse to avoid doing warranty work.
Something like a Banks chip could reasonably be construed as being a cause of many sorts of powertrain breakdowns, since it does inherently place parts under greater stress than the original factory settings. On the other hand, it should have no bearing on a breakdown in, say, the steering components.
Right on Drew,
Armed with both sides of the equation decisions are a bit easier. Premier manufacturers of aftermarket parts work pretty hard to avoid any conflict with OEM warranties.
In the end it's the buyers decision. I've had two banks kits including the transmission chip installed and was never denied any Ford service or warranty work. One was when the transmission wouldn't go into overdrive. Not one word about the Banks, ... in fact they praised it.
