I've heard all about tuners for a while now and was really interested but just about a month ago on a TV auto show the guy said that tuners will void any warranty AND that the dealerships can now see from the computer any history of tuners being used. Seems to me if saving on fuel costs is your goal, you probably should buy less truck. Removing the emissions controls is just plain irresponsible.

Correct me if im wrong, but only the 2013+ trucks will be able to see if a tune was applied?? And not ALL warranty would be void i dont think. It only affects the parts that the tuner would have affected or changed??

Not quite true...
while the later vehicles have better diagnostics and tracking...
even before that most good mechanic with the right tools can tell when boost, or egt's or fueling or....
is out of 'normal' range - some noted different burn patterns on pistons...
our early 2011 Audi was flagged as having been tuned for warranty consideration - but we didn't have any issues and trading it in anyway
