40 roll - CTS-V is running headers, smaller pulley, tune, cam, and some other mods. The owner of the CTS-V is a friend and he also has a dedicated TT mustang drag car. The diesel put about 5 cars on the V.
I find it curious the E chassis got the M57. The information available on wiki doesn't seem right, which cars got the N57 then? It seems like the B57 is the next diesel engine to coincide with their petrol modular engine program, so it appears the diesel never go their version of the "N55"?
