Tuning hasn't ever voided a warranty on any car I've ever owned. It can cause grief if your service manager is a prick, but if you have a good one that understands what a tune actually does, you shouldn't have any issues.

Actually I've heard Ford has put out a TSB that tuning WILL now void your warranty.

Well shoot I am already screwed then if that is the case. Might as well go tune! lol.

I have heard though that the cause of failure what ever it may be must be linked back to what modification was done to cause the failure. Obviously an engine tune won't cause something somewhere else like in the differential to fail spontaneously.

It seems like such a grey area... blah.... sooo tempted to tune...
