Anyone running anything other than the GM management system for the LS3 crate motor? Is it possible to buy an 08 Vette Harness and PCM and turn it into a stand alone harness? Looking for a tunable solution to the LS3 crate motors.

Yes, that solution will work. You can change the factory harness to stand-alone, and then program the computer to your hearts content.
It has also been shown already that the GM Management system can be programmed with a factory VIN # and then reprogrammed also.
