I finally got around to ordering new injector nozzles for my SD. I decided I'd try the Bosios from DieselGiant, since I've read the horror stories about the Bosch remans.

Before:
Typical light diesel smoke upon start up.
Sluggish off the line, but not that bad. (ALDA has been turned up)
Light nailing from idle up to 2500 rpm

After:
Almost no diesel smoke upon start up
No where near sluggish anymore, even when cold.
Very light nailing only at idle. Which I've heard is supposed to go away after a few hunderd miles of "breaking them in".
Much more power.

In short I would recomend the Bosio injector nozzles to anyone who has the original nozzles in their car. They breathed new life into my motor and gave me power that I never knew I had. You will not be dissappointed. Best $180 I've spent on the car.
