When I had my Vance and Hines power chamber pipes with Rinehart exhaust pipes installed on my 2011 triglide I had them put on a throttlepak which was to take out the delay which I couldn't tell any differance with it or without it. The dealer said it might void my warrenty. thinking about taking it off. if I do and I don't take it to the shop to have it done. Do I need to have them adjust it or remap it or what.
