make a separate controller and install an electronic VG turbo (newer 400-series) and it may beat the 871. .. but you still have to contend with any junky replacement parts.

So, it is vgt turbo that is making such a big difference? Is there anything else important too? On old n14 fuel pump is really simple, but on my cm870 it is higher pressure with actuators and stuff. Is it better for mpg as well?
