one thing i don't understand is that with 2 turbos ( one after the other) I would think it would build a lot of low end torque. but its peak torque happens at 2000 rpms whereas the duramax is @ 1600 and i believe the cummins is even lower than that. the cummins and duramax run comparable hp and torque numbers as the 6.4 with only one turbo. why all the extra parts?
