I'm not bashing Livernois. They put out some good tunes and do good work. But there are plenty of good tuners out there that don't lock your ECM. Mine was tuned by Livernois when I purchased the car (unknown to me). Then when I did my DOD delete and cam install, I found out my ECM was locked. It was either send them my ECM and pay them to unlock it or just buy a new ECM. FYI, it was cheaper to buy a new ECM and have my VIN re-flashed from Pace.

Ultimately, it's your car and you can do whatever you want with it, but now you've at least got some extra information from myself and other members to help you make an informed decision.
Been there done that.
