Included in most Whipple Hellcat based 3.0L and 3.8L complete kits, this T-MAP Extension with Intercept relocates the boost signal from the front lid map sensor to the rear map sensor preventing limp modes caused by the instability of this reading. Not all complete and NFT kits include this sensor relocation harness, and it is not included in Hot Rod or Dragpak race kits but it is necessary for tuning on the factory Hellcat PCM.
