I haven`t been on here in a while but thought i would pass on an experience i`m having. I just bought a 2007 dually six speed and put a triple dog downloader in it. I will admit that the truck performed well with it but i took it back to stock yesterday to update it on the computer. After i returned the truck to stock it tripped a couple of codes. One was a speed sensor and i`m not sure about the other yet. I had a check engine light,abs light,parking brake light,airbag light all lit up in the dash not to mention my speedo quit and i lost my brake lights. I was on the phone with bully dog for over an hour and they told me to disconect the battery for an hour and i should be fine. Well it wasn`t so the truck is now at the dealer and they said they`re not sure what they can do cause they feel that the computer has bee tampered with. I`m keeping my fingers crossed that it will be fixed and i`ll still have a warrenty. I realize i took a risk in doing this mod as we all do but would hate to see someonels go through this as well. Just thought i`d pass this on. Ted
