Yes, might one put in too much diesel and "choke" the ensuing burn? I'm running the old-fashioned AAZ engine with the VE-pump, and I'm wondering if there is any thing in the combo keeping the stoichiometry straight. It is known that keeping the revs low save a lot of fuel, but might being to hard on the gas pedal counteract this effect?

Does too much gas pedal oversaturate at low revs?

So, I've schooled myself on the VE-pump here, Robert Bosch type VE Diesel injection pump, and so I know the fuel pump's control sleeve is what regulates the amount of fuel per cylinder. The control sleeve does this by alternating the length of injection. As I understand, the injection pressure, created by the plunger, stays the same, which makes total amount injected a function of time. This, however, does not explain if the pump will allow for over-saturation.
I don't know if there is extra power to be had from over-saturating the air with diesel. If there is not, then I guess Bosch would design the pump as not to oversaturate, and if there is extra power to be had, to oversaturate when gunned.

if you are stock. the injectors nozzle holes can only let x amount of fuel in. letting more fuel in by giving more fuel time IS over-saturating will miss the burn window - and you will just soot up.
