If you install an intercooler (good one), then just adjust the full load to maximum. Adjusting ALDA just affects to low revs when boost is not up, it is usefull when you have bigger turbo and maybe modified pump with bigger elements, but with stock parts it doesn't make that much difference. Ofcourse it will increase the feel of power, but just the feel.

The pump with stock elements (5.5 mm) can only deliver 60 mm3 / 1000 strokes, it is enough for 180 hp, if we are talking about OM603. This power can be achieved without intercooler, but it will destroy your cylinder head in the summertime. I know

When you adjust the full load, then you should consider about the timing too, maybe try one or two degrees earlier that normally, you will see if it works.

And if you are thinking about tuning you diesels up some more, then I can help you. We in Finland can make you all the parts necessary, and lots of cheaper and totally better than Mosselmann.

Suitable turbo's, exchaus manifolds, tuned injection pumps (load for 130 mm3 -> 450-500 hp), GOOD intercoolers etc. We can make it all.

ps, sorry for my english, I'm better in finish

pps. Oh yeah, be carefully when you add the boost with stock turbo, they are so tiny that more than 1 bar only increases the pressure of exchaus manifold, and that kills your engine. Stock boost 0.75-0.95 (depends on model) in enough for everything the pump can deliver, if you have good IC.

Sorry about the metrics...
