DiabloSport inTune i3 Platinum + Modified PCM Kit for 2021 Dodge Charger R/T 5.7L and SRT 6.4L, Chrysler 300 (PKITCHARV821-I3)

This DiabloSport combo pairs a modified PCM with an inTune i3 tuner for compatible 2021 Dodge Charger R/T 5.7L and SRT 6.4L applications and Chrysler 300 fitment as stated. It provides access to performance tunes and user adjustments; save the stock calibration with the tuner before removing the factory PCM.

Overview

The factory PCM on the specified 2021 Dodge Charger HEMI applications is locked against aftermarket tuning. The modified PCM provides the foundation needed to load performance tunes.

The combo includes an inTune i3 with preloaded tunes and end-user adjustments, including 93-octane and 91-octane engine tunes and a performance TCM tune for the 8-speed transmission.

The listed performance gains are up to 20 rwhp and 18 rwtq, with 25 rwhp on the 6.4L, on 93-octane fuel.

Save the stock calibration with the tuning device before removing the factory PCM. Modified PCMs are not compatible with other tuning brands.
