[Vwdiesel] Drive it hard-Drive it easy?

[mikitka]

 One thing I have noticed with my 91 ECO jetta converted to a turbo is that
if I drive it easy for a few tanks of diesel and then get on it hard it will
pour out the tail pipe with black smoke. Almost to the point that I can't
see the car behind me, now this only last for the first two good hard full
throttles, then it goes down to a lighter black basically not much but
enough to notice. This will stay that way if I keep driving it hard, but go
just a tank of driving easy then back to the heavy black smoke for a bit
until it clears it out.

Odd to think of that much of a build up on the turbo and exhaust system for
it to get blown out under hard acceleration.  Also remember I do not have a
governor on mine, it was removed when I had the pump overhauled by Giles, so
I'm careful not to over do it. Not to mention the K14 isn't very efficient
anyway at high boost for long.
