Bully Dog Power Pup on 6.7

Anyone have one of these yet on their 6. 7L? What kind of performance results in terms of mileage improvements you're seeing? Any issues with warranty service caused by them detecting the downloaders presence?

I have one and saw about 1 mpg and better power, but louder timming noises.

Have you had to take your's in for any warranty service since you had it installed? Were they able to detect that you had had it installed?

If they can detect it on all previous trucks, i don't think they'll have a problem on the newer ones that have more sophisticated computers... . but i dont think anyone knows for sure as of yet.

Yes, I've been in three times for codes and the G30. I went back to stock and nothing was ever said by the dealer.
