planning to do the whole sha-bang some time in the near future. im adding a cobb catted dp, cobb ebcs, and fuel pump, along with a already modded borla cat back and cobb sf intake on my 03 wrx. question is if i get that dyno'd could i add a catless up later without having to re tune? or would i have to do the up and dp at the same time? its more of a $$$ problem, so i might have to wait till' spring. any help would be coo! :D
