i was looking to buy a chip for my truck 05 cummins HO, but i can not decied wich one to buy. The edge chip looks good espically with the incab controller but i was wondering what you guys were running and how you liked it. one more thing i know that a chip will void the wararnty so i would pull it out if i ever took it back for warranty work. What about the egt plug that has to be installed in the manifold?? I am guessing that i could just put some kind of cap in there, but would the dealer still void the warranty?? Thanks for all your help, Guy
