    Questions about the northstar 4.6 engine and chip

    so I recentlly bought a 2004 pontiac bonneville gxp. It has the 4.6 v8 rated at 275hp. now Its detuned somehow and I had heard that the computer is locked and can't be cracked, so its impossible to get a chip for it. Is this true? anyone know of a way to get around this?
