According to that engine ser#, your engine (CPL8518) IS already signature-600 build. It just was not sold as one, having a 565,1850 program in it when it was installed into the vehicle. All parts internally, and also the VG turbo are already at the highest tier. It is simply a matter of putting a compatible 600HP program in it.

does it still have the VG turbo on it? -- or some aftermarket garbage?. You have not been very clear on what has been done to that engine. Maybe take a pic or 2 of the exhaust and intake sides of the engine and post them if your not sure.

My apologies. I took it to a trusted shop right after I had the motor inframed. It was completely stock. After the tune was installed I bought a plug kit online and put a plate over the exhaust finger where the EGR valve was and another over the intake where the EGR tied in. I left the EGR cooler on so I'd still have proper coolant flow. I've been meaning to plumb it in rather than rely on the cooler. I removed the EGR and circulation tube that came off the cooler and wrapped around the motor going into the intake. My goal was to clean up the motor as well so it was simpler and easier to work on.
