So im swapping a TR6060 from a 2010 Camaro ss into my 09 G8 GT. I have bought the complete engine harness out of a GXPM6 that plugs straight into the E38 and has all the connector provisions for the tr6060. So my question is, what do i need to do on HP tuners to get the car started and driving. I heard some people needing to grab files from Holden Commodores, why wouldnt i just be able to reprogram the ECM with a file from a GXP? Is the BCM going to be pissed(need to be reprogrammed too?) Im sure there are things im missing that i dont even know about. Any help is appreciated.
Mike.
