Should read, "We lock up our PCMs so tight you can't do **** with them".
Apparently Holley has set their sights on 3rd gen Hemi swaps. Mopar's stranglehold on PCM coding is about to be broken.
All of the modern hemi performance shops offer unlocked PCM's for the last few years. HHP, Forza Performance & Tuning, Diablo Motorsports, etc. all will unlock your PCM and/or sell an unlocked PCM to you so you can keep your original PCM. All of these shops offer just about any custom tune that you want on your PCM.
