Kevin,

If you don't want to touch the ALDA, you have two choices:

1) remove the injection pump and have it calibrated at a Bosch shop

2) Get used to having a sluggish car that is not how Mercedes engineers intended it to operate.


FYI, if for some freak reason you damage the ALDA, you can usually find one at a salvage yard cheap. They're all the same on 617, 602, and 603 turbo engines through at least 1987. Also, another option is to remove the ALDA and insert an extra shim underneath... this is a PITA, as you will need to fine-tune the shim thickness by filing it, etc to simulate turning the ALDA shaft screw. I long ago gave up on trying to leave the ALDA tamper seal in place! Just not worth the hassle...

:p :p
