Important Notes-

  • This kit requires you to send your Engine Control Module (ECM) & Transmission Control Module (TCM) back to Magnusun so they can install a supercharger specific tune. You may also choose to have a more aggressive custom tune done at a qualified shop (at customers cost).
  • A sales rep will contact you after your order to fill out a calibration sheet for Magnusun and confirm your order.
