Well truck developed a miss the other day so I took the BULLY DOG power pup downloader and removed the programing for my truck back to stock. Well come to find out it had a bad piston in number 5 cylinder, and the dealer said that they could tell that the truck had been reflashed with a different program. They couldn't actually tell what the program was but the could tell what the max fuel pressure was and they could tell that the fuel curve was not in check with factory programing.
And yes I know that when I put aftermarket performance items on I am taking a risk of my warrenty being denied. But I want to let everyone else know that when BULLY DOG tells you that there is no way that the dealer will be able to see that you had reprogramed the computer that they are full of fecal matter. So I guess that if anyone out there is looking to buy a BULLY DOG DOWN LOADER and is worried about your warrenty I would suggest something different!!!
