Most local Houston shops don't offer pcm unlocking (chrysler gpec2/2a, gm t87a/t93, e41/e90/e93) as a bench service — they'd send the part to someone like us anyway. Going direct saves the markup and shortens the timeline. Total round-trip from Houston: typically 5-7 days.

No — we only unlock it. Tuning is a separate skill set and we deliberately stay out of the calibration / dyno-tuning business. After we unlock, you (or your tuner) flash whatever calibration you want using HP Tuners, EFILive, DiabloSport, or similar.

The unlock itself isn't outwardly visible — the module operates identically and reports normally to OBD-II. However, if you flash a non-stock tune AFTER unlocking, the dealer scan tool will see modified calibration values. To return to dealer-detectable-stock state, use our Stock OEM Re-Programming service.

Unlock = removes the security so the module can be tuned. Stock Re-Programming = flashes the module back to factory OEM calibration. You'd use unlock BEFORE tuning, and stock re-programming AFTER (e.g., before selling, before warranty work, or after a failed tune).
