I can't see how incomplete combustion could create more exhaust gas pressure/volume than complete combustion and maintain efficiency and low-end power.

One of our Members Dr. Bert and likely more of our Members advance the timing as much as 28 degrees BTDC and claim it gets better performance.
I did 27 degrees BTDC and it was slightly peppier when you applied the Pedal but mine was too noisy for Me at idle (using Diesel Fuel). But, I think that puts to rest the retarded timing being needed to spool the Trubo better.
