Welcome to the club!
One other thing, I would suggest is to join the MB Club of America at mbca.org and go to your local chapter meetings. You will meet lots of people who know and love these cars and can you can learn many tricks from them...
Good Luck.
BTW, on my 300 SD I just backed the ALDA screw out 1/2 turn and it made a world of difference in off the line power. I also had a mechanical boost controller set at 14psi (to go any higher without more fuel is a waste)
On the OM603 I have now in the SDL I just removed the ALDA.
I also blocked off the EGR and ARV valves. If you take the EGR valve off the intake, the hole is the perfect size to be blocked by a quarter. I went all 'authentic' and stuck a 1981 quarter in my 1981 300SD
