Forced is lacking practical experience on this subject.

Cummins is DI and Merc is not. I'm pretty sure Cummins is designed from the beginning to have high backpressure all the time for emission control reasons. It also has a way better fuel injection and timing systems than these. The system has been built to operate that way.

OM605/6 don't like high backpressure. As the timing device is from the stone age, we are limited to use a certain base timing which can't be altered to work optimally with driving conditions, other than rpm. Now this is ok with stock pumps where fueling amounts won't alter that much, but it's a different story when getting high hp.

My engine dies totally every time EMP goes about 15psi higher than boost. It "works" but feels like blowing into a bottle. Whether it was 5psi/20psi or 30psi/45psi. The same thing with 2 different turbos and 2 different injection pumps. The other reason why high backpressure is unwanted are the stock exhaust valve retaining springs.
