Ported Plenum

I have a ported plenum that I want to put on and was wondering if I need a retune? I have a conservative tune now on a stage IV port, SBTB and a Airaid CAI + 6# LP, LT headers.
Thanks

put it this way u cant put any more air into the plenum then ur TB will allow if u have a SBTB then it will allow a shyt load more then a stocker but u cant gain enough of anything to worry from a ported stocker
