Fixing to put on some Rinehart eagle pipes....Been told to have it re-mapped and stage 1. I figure the re-mapping is re programming the computer etc...Is the stage 1 just the air filter or what ? Open to any other advice.

 

Stage 1 is pipes air and fuel management. wether you remap at the dealer or get an aftermarket system like pc111 or Vance and Hines fuelpak or one of the other ones you need something to tell the computer on the fuel injection to mix the right amount of air and fuel for the newly opened up pipes and air intake that IS REQUIRED to make these babies work properly.
