I never really thought much about it but after I picked up this 300SD I realize that something must be up with my 300D Turbo. The 300SD takes off like a banshee and the turbo whines so well it's great! But not so much on the 300D. I've been reading a lot lately about slow performance on take off and am considering either buying new injectors or rebuilding mine. I have done a lot of work to the 123 but it still takes off slow. At high RPM's on the highway it accelerates well. Also, I can never hear my Turbo whine. Here's what I do know:

1) Valves have been adjusted.
2) I am taking off in 1st.
3) The linkage looks good.
4) New air filter.

I have been reading a little bit about the ALDA but am still not too familiar with what it does or why and how to adjust it. Anything else I should consider related to getting better take off?
