So as some of you guys know I have thought for years my PCM was locked by the tuner.. The last shop to tune my car(since I've owned it) said they could not tune it because the PCM was locked and said my only option was a stand alone PCM(which died on me last summer) to run the nitrous tune... Appears I was either lied to or they don't know shit. I emailed the tuner today to ask how to unlock the PCM, here was his response(BTW it was Ed Wright who put the current tune in the car 6-7 years ago):
"Who told you it was locked? Anybody can tune it, no problem. If LS1 Edit has a problem reading it just use something else, or write over it with another tuning file. If your tuner uses LS1Edit just tell him to flash it with one of his own files and tune away. If uses something else he won't have any problems. Nothing I ever did would keep other people from programming the PCM."
