alda remove. I adjusted mine, big help, took it off and gained a little more. Make sure the banjo bolt and line to alda is clear. If taking alda off this is a good connection for a boost gauge.

Adjust boost, mine was three psi low, raised it to factory specs. not a great improvement but noticable.

EGR delete, no differance in power,at least not seat of the pants, perhaps a dyno would show it. Helps keep intake cleaner though.

Next step adjust IP. On the 240 this is not much trouble, but the 300 you will need to remove the oil filter to get to it. I think there is a sticky on it. If not superturbodiesel does have a sticky on it.

Adjusting the IP for more fuel did make quite a differance on my 240. the 300 I never did mess with it.The other things gave me enough.
