I'm curious to know what folks are getting for their 0-60 time on their 1990-1993 300D. Spec, at least on the 93, is 12.8 seconds. A few years ago when I did mine, I was at 15 on the 91 and 14 on the 92, if I remember correctly. Now the 92 has 244k miles, just had a head gasket replaced, and I'm in the 16-17 second range. Trying to gauge whether something is amiss or car is simple getting old.

To answer a couple of obvious questions....1. No, I have never adjusted the ALDA.....2. I am glad to convert to pressure-actuated wastegate when the need arises, but haven't done it yet.
