Hi guys,

I am trying to fix my 1985 300D W123 and make it more drivable.
I did adjusted the valves, Diesel purge, banjo bolt clean, air filter, fuel filter... The basic on good tune up.

Car is better than when I got it, but It is still very sluggish specially below 2000RPM. I start boosting at 2000 RPM and will boost 8-9 psi max boost.

I am still learning on those engine and found out about the Alda.
Mine doesn't hold Vaccum. I guess it's shot.

Will removing it make my car faster ? what exactly to I have to do.
I would like to disable the EGR also.
I don't mind adding a manual boost controller and running a boost gauge to make sure I doesn't over boost.

As it is now, It's not a fun car to drive. I know it will never be as fast my TDI but Do I really have to slow down the traffic when I drive a 300D ?

I also have intermittent leak on my prime pump. Anybody as a part number so I can order one from the dealer.

One more thing when my car shift, sometimes not always I hear from the transmission a whistling sound. I know it runs on vaccum but should I hear it working ?

Thanks guys.
