It sounds like your cats may be clogged and need to be replaced. Since you did change altitude quite a bit you might try resetting the computer. Im not sure if its just the usual disconnecting the battery for a few hours. It might be different because of the chip. It may be programmed just for the altitude where it was. See what you can find out on the chip and go from there.
