BTW: I think the difference between EGTs from bank to bank is often caused by variances in fuel injector delivery. Having flowed 3 different sets of these old (circa 1973) Volvo/Mercedes style injectors before, I can tell you that they have a wide range of flow values.
It’s a shame that no one has yet adapted (at least for general consumption) either the Brucato or PPE ECUs to run some nice modern injectors like the ID “X” series, which are far superior, with all stainless internals, flow matched, etc, and are actually cheaper than these ancient Bosch hose feeds we use.
I’m thinking that all that would be needed would be to install the necessary drivers in the ECU and then come up with a base tune for those injectors, and the only other things would be needed would be a custom rail and harness (or adaptors).

Here are the fuel injector pulse traces:

As you can see, the line is a fairly steady slope throughout the run, with no funky spikes or dips.

If those old Bosch injectors are high Imp 12-14 ohms then the drivers in the ecu are not the problem.
