It's sad that we have to work on a Hemi to best a damn v-6 but weight makes a difference. The warrenty issue is a problem. I was going to replace my tb with a ported and polshed unit. I asked the service manager/ warranty guy about the swap. He told me that if there were a problem, i.e., detination and piston damage ANY part that comes in contact with gas, as in intake to cats. the warranty is voided. If I were to reprogram, same deal. If they flash it and it comes up on history as reprogrammed, voided warranty. He left and I talked to the service writter I always use and he told me that they monitor the forums. Dodge must be desperate! I love the way they beat the dog#*^t out of the cars in commercials like decorating the tree with the silver RT. I don't think George Washinton would have been to happy when Dodge voids his warranty for going off road with his Challenger!Lol
