This may not be the case but I reckon that if you re-chip ya XR6T or XR8 or GT, Ford may void ya warranty. Changing cam spec's, tyre thickness, injectors, exhaust etc will effect all other components on vehicle(sometimes dramatically). ie. axles, box, brakes etc. Just curious to see what Ford have to say about the matter.

I think you'll find that any manufacturer has the right to void a warranty for almost any mods. Weather they do or not is more of an individual case by case thing.

I have met quite a few people that have modded their new cars quite extensively, but have managed to keep their warranty mainly due to a good relationship with their dealer.

IMO, if you are open and honest with your dealer, and don't try and BS them or hide the mods, most dealers will be responsive to that, and honour the warranty, provided the mods didn't directly cause the issues.

Quit different here in the states. they are cracking down on modding of the cars. With SVT cars especially. You chip it you automatically void your warranty. One guy blew up his engine in his 03 Cobra and since he chipped it they told him tough titty. Sad part is that the problem was not caused by the chipping. But alas you are fighting a losing battle here in the states with that.

I want to mod the hell out of my Cobra, but am waiting a bit until I can afford to pay for a new complete engine and then start. Safest bet by far.

Pretty sad, but safest
