Anchorage does have a TDR group. If you come out the the Palmer drag strip next Wednesday there should be a few of us out there. As far as power enhancements go for your 03, I'd PM "AK Ram". He has a twin turbo'd 03 with several go-fast goodies on it and could point you in the right direction.
Fill out your sig so we have more details on your truck, standard, auto, gear ratio, modifications done so far, etc, etc... .
