Re: Mods and warranty!
Spoke to workshop foreman of one of the dealerships a couple of days ago. The bottom line from Ford was that the driveline will not be covered if any more than a cats back system is fitted. This meant no CAI or chips etc. As said above, be nice to those who service your car. You want them on your side.
The bottom line though, is that it doesn't matter how good or reputable the people are fitting the gear, You make too much power, you can be refused warranty on the affected parts(driveline). I guess they have to draw a line somewhere, even if the XR8 runs the same trans and diff as the GT.
