A Piezo and POD could both be injecting the same amount of fuel with the same turbo, and the Piezo would be making less smoke and more power every time. Becase it is a more efficient injector.

I never said that an efficient turbo wasn't as important as an efficient injection system, but turbo efficiency isn't part of the diminishing-returns equation germane to smoke; if you could assume a 100% efficient injection system, there would be no diminishing-return equation germane to smoke.

Only atomized fuel can burn. Injector inefficiency states that only a given percentage of the injected fuel is atomized in the combustion chamber; you have to let yourself not-burn some fuel so you can-burn the fuel that came with it.

By supplying enough high-pressure air, turbochargers can force fuel to be atomized. But that's an inheirently inefficient process; it takes time, which an engine at high-RPM doesn't have.

Exactly

Depends on what your wanting to achieve and what the end result is going to be for the truck. Is it a racer or daily driver. Tow or weekend play. Hole size and quantity play a big part. Pretty much all the aftermarket injector builders have similar high efficiency ratings for each different size injector due to the balanced and matched sets. I've heard that the Bullydog injectors arent as well picked in a set as most others. I prefer Mcswarz Diesel Engineering injectors. He will build you new ones to whatever spec you want or take your stocker's and balance them
