okay, im ready to start giving the bird more power and it seems to me this is my first of many upgrades. im starting with the pipes i want to order hmf big bird low mount carbons ,now do i need to ask about mapping or do i buy a powercommander or yosh ems? also does the powercommander install have to be done by the dealer.( bear with me this is my first fi bike im used to a pipe and jet kit.) im also planning some engine mods over the winter but right now shes stock will she run ok with the big bird exhuast? any advice would be helpful.
