SW has some good suggestions. In addition to these, I would make certain that the various linkage--from the accelerator to the injector--is nice and tight. When I got my 300D turbo, it was dreadfully sluggish, quite unlike what a turbocharged 5-cylinder should be. I adjusted the linkage, changed filters, cleaned the banjo fittings, etc., and now she does a respectable 13.5 from 0-60.
