ALDA and Boost Adjustment Q's.

[Elripster]

I would like to tinker with the boost on my 82 300SD but I have a few questions.

1) Where is the waste gate actually adjusted?

2) Where is the ALDA and where is it adjusted?

3) Where can I measure the turbo's boost? I have a pressure/vacuum gauge and reads up to about 30PSI, but I don't know where to tap into.

4) Is there a certain RPM I should use for measuring boost?

From other posts I got the max pressure to be about 13.5psi and plenty of info on adjusting the ALDA.

Thanks,
Frank
