He said Ford is not screwing around with warranty and tuners.

I would have thought if anything I would be doing them a favour by monitoring temps and such and would be preventing anything bad from happening by knowing what my truck was doing. What do you guys think????

We can only talk about US laws. Under those, Ford has to PROVE that your modification caused the failure. This topic is covered in the FAQs on PHP's website. Canada may well have a different outlook on things.

Yes, a dealership CAN tell if a programmer has been used on your truck, if they are suspicious and want to go to that trouble if there is a failure.

And, in another post in this forum, PHP admits to 2 or 3 failures in something like 160,000 tuned vehicles. You can find that data at the end of this thread: http://forum.gopowerhungry.com/1999-...re-survey.html

I honestly would not worry about one of Bill's tunes hurting your truck. There's too many of us who are happily using his tunes, including Bill himself.
