My experience with diesels is that overfueling will increase power.

There is a point of diminishing returns, but going beyond the normal no-smoke point to where you get smoke will increase power.

With this increase of power comes: More fuel consumption, Higher EGT, More Smoke.

You will see high-performance diesels belching smoke, because the easiest and cheapest way to get more power is more fuel, it produces more heat which is more power. To do it properly you of course want more boost and an intercooler/aftercooler, the cooler air into the cylinder means higher density = more oxygen/heat/expansion/power.

Removing the Alda is IMO not necessary unless something is wrong with it.

The Alda/aneroid is there to prevent overfueling and therefore smoke on takeoff, simply put it is a way for a mechanical injection system to fuel the engine efficiently with little-no boost (idle & low RPM) and then compensate for the additional fuel necessary at higher boost. Since it is designed to LEAN the mixture without boost, its default is to fuel as if there were max. factory boost at all throttle settings, or in other words the absence of the ALDA will cause the IP to assume that there is max boost all of the time which will be a rich mixture at low boost. Heavily over-fueled off-boost can cause hesitation, lots of carbon, possibly ring fouling.

If you remove the aneroid so that you can control fuel completely with your foot, you can come off idle with such a shot of fuel that it will sputter.

Personally, I feel that a properly operating and adjusted ALDA is good. More off-boost power can be had by overfueling, which removal of the ALDA or over-adjustment of the ALDA can provide, but it should not affect the full-boost power/mixture.
