Does anyone in the North Dallas area accidentally know of any performance shops (or other places) in our area you would trust and recommend? I've got a bone stock 03 with 60k miles that I would like to do a few small mods on (lower pulley swap, new plugs, and tune) but have had a difficult time finding anyone around here that has any experience with HD's or Lightnings. (I assume if I go to the dealership for the plugs they will want to use stock plugs with the stock gap that would lead to problems if I changed the lower pulley on the supercharger afterwards.)

Thanks
