Then from there started me a base. Most tuners DO NOT lock their tunes. On a GM ECU, locking actually changes the seed/key and renders the PCM useless to anyone but the original tuner (as in it can’t even be reflashed PERIOD). It’s really not a nice thing to do. The only time I could even see doing it is if you were offering some sort of warranty on the vehicle and you didn’t want the customer to mess with the tune. --- _[View the full topic](https://forums.speedlife.net/t/the-shop-ct-stay-away/261300)._
