Adding FRPP shortys after Procharger

[blazen71]

Hello all, I've got an 03 Marauder that I installed a D1SC Procharger on. I want to install FRPP shortys and an off road X-pipe(I already know they'll fit) and was wondering if I would absolutely need a dyno tune. I would like to get away without one. Thanks

Yes you will. The flow of those two components is enough to change your A/F.
